Bonjour ! Avec Windows 10 et Photoshop CC 2024 l'outil lasso polygonal refuse les retours arrière.

Pourriez-vous me dire ce qui peut causer ce problème assez désagréable s'il vous plait ?

Cordialement

Photoshop Beta version 26.8 M3390 fixed this problem. It works good

Hey, @Zafer37586609c1kv. Welcome to the Photoshop Community. I'll help you figure this out. 

 

As a test, try using the Polygonal Lasso tool with the Shift key to draw straight lines before using backspace to erase. If that does not work, reset the Polygonal Lasso tool itself. Right-click on the P. Lasso Tool icon in the Toolbar menu and select Reset Tool.

I just launched PS 2025, and unfortunately the Magnetic, as well as the Polygon Lasso tool are bugged. When selecting with the lasso, I cannot move the viewport by holding down [SPACE]. When using the magnetic lasso, I cannot undo the previews points by hitting [BACKSPACE] anymore, as it was practice in all previous PS editions.

 

I really wonder, do they do Product QA before releasing new builds? I imagine they are using AI heavily not only for creative purposes but also in technical fields, like bug finding. Even if the QA department consists of humans only, a quick tour of all tools should have revealed flaws.

 

Being a adobe user since more than 25 years I'm really intruiged where this company is heading...

Hi there,

 

We're sorry for the trouble caused you. Since you are seeing this issue after the latest update, I just want you to reset Photoshop preferences back to defaults and check if you are still seeing the same problem. Sometimes the bad preferences make things weird in the program. We really appreciate the time you have given to Adobe products. 25 years is a long journey. Let me know the status.

Thank you for your help. Indeed I have not yet had a tool blockage using the lock key. For the reset I have no effect on the tool with this word because it does not appear.
Kind regards

Bonsoir à toutes et tous !

Me voici de retour et cette fois avec la version Photoshop 2025.

Rien à faire j'ai de gros soucis avec l'outil  lasso polygonal qui lorsqu'il ne se permet pas de sélectionner ce qu'il veut refuse les retours arrière.

On m'a conseillé de le faire en appuyant sur un autre touche en même temps sur mon clavier mais non  cet outil refuse.

Est-ce que quelqu'un connait une astuce pour que l'on puisse voir correctement les crans de la règle ?

Moi j'ai vraiment du mal à distinguer car j'ai besoin de précisions souvent.

Merci si vous pouvez m'aider !

Courtoisement

Cordialement

I've been using Photoshop since 1994, but the problem that's bothering me right now is that when I use the Polygon Lasso tool, the Space and BackSpace keys often don't work at all, just like the problem the author mentioned above.

I've been having this ridiculous problem for over two years now, where I'll be working intently for over a minute, tracing the outline of an image with the Polygon Lasso tool, and then when I try to move the screen with the Space key, neither the keyboard nor the mouse buttons work and there are tons of people in the Adobe community raising issues about this, but Adobe officials just throw their hands up in the air because they've never experienced it and can't reproduce the symptoms.

 

All Adobe has been saying is that you can reset your preferences, but that doesn't work at all - not even if you reset three or four times, not even if you update your graphics card drivers, not even if you format your computer, reinstall Windows, and then install and run Photoshop right away.
I'm not paying for Photoshop to work on one or two photos, I'm working in Photoshop with over 200 layers in my main working PSD and dozens of clipping masks and adjustment layers, and I'm supposed to just open up a few photos with barely a single layer, test them out, and then sit back and say the problem isn't reproducible?

Bonjour,

J'ai exactement le même problème, 9 fois sur 10, l'outil lasso polygonal, refuse l'utilisation de la barre espace pour déplacement sur l'image et la touche suppr qui permet de modifier le dernier point d'ancrage... Mais curieusement, parfois cela fonctionne (rarement) normalement.

Rien n'y fait, que ce soit en réinitialisant l'outil ou même en réinitialisant l'ensemble des préférences de photoshop.

Cela rend l'utilisation de cet outil assez pénible alors que je m'en sert beaucoup.

Quelqu'un a-t-il le même problème?

Je vois que THOMAS60 remercie, en précisant que cela fonctionne, mais je ne vois pas de réponse lui suggérant de solution...

Je tourne actuellement sous la dernière mise à jour de Photoshop 2025 (V26.1) mais cela le faisait déja depuis quelques temps.

 

Merci d'avance pour votre aide,

Bien cordialement,

David R

Bonsoir Monsieur David R !
En effet j'ai eu parfois la réussite de voir ce lasso polygonal faire des retours en arrière.
Super, !
Sauf que lorsque c'est fini et bien cela recommence.
Hier j'ai eu un mal fou à pouvoir revenir en arrière.
La réinitialisation de l'outil ne solutionne absolument rien.
Alors je tempête devant Photoshop car il n'y a pas que ce souci à devoir résoudre.
En faire la liste je n'en ai pas le temps.
Dommage !
Peut-être que pendant 2025 ce seront que de mauvais souvenirs.
Courage et espoir à vous !
Bonne soirée !
Cordialement

Hi! I have been having similar problems with the polygon lasso tool. I am no longer able to delete the last point or escape the tool when I start the selection. Panning with the spacebar also doesn't work when the selection is started. Tried to reset the tool but didn't help...

Facing the same issue since multiple number of days. The only solution that has worked for me so far is minimizing the program and then using it again. But that shouldn't be the solution. Adobe needs to do something with such a bug in one of their oldest tools.

Bug report template:

Issue

  • Photoshop version: 25.12.1
  • OS: win


Steps to reproduce:

  1. select lasso tool (switch it to polygon lasso mode)
  2. click down a few points, now while still in lasso mode...to put down another point
    attempt to use the space bar (hand to pan the screen)...doesn't work.
  3. Sometimes it does..sometimes not
  4. this also seems to bug out the "backspace key" that allows for removal of the last point(s)
    clicked down.

 

Expected result
Actual result: works like it used to.

I may have solved the problem. Click on Edit > Keyboard Shortcuts > then in drop-down choose Shortcuts for Tools. Check the box Use Legacy Undo Shortcuts. See image. I have not experimented enough to know if I ruined something else. I am using version 26.2.0 on a PC.

@Makko29421141abep I noticed the issue with the backspace not working for the polygonal lasso tool, I tried renaming the Photoshop settings folder to Adobe Photoshop 2025 Settingsold, location here

C:\Users\username\AppData\Roaming\Adobe\Adobe Photoshop 2025

Relaunched Photoshop and still have the issue, closed Photoshop, deleted the newly created settings folder and renamed the Adobe Photoshop 2025 Settingsold back to Adobe Photoshop 2025 Settings, relaunched Photoshop again and the backspace key starting working again.

Bonsoir et merci pour votre information !
Me plaignant depuis des mois à ce sujet pour les mêmes problèmes avec ce lasso polygonal je ne peux MALHEUREUSEMENT RIEN vous apporter afin de vous aider !
Comme à toute la communauté je relance un appel pour pouvoir retrouver les retours arrière de cet outil qui commence sérieusement à m'aiguiser les nerfs !
Merci à ceux qui savent comment opérer car s'il n'y avait que cet outil qui se figeait mais c'est tout le logiciel parfois !
Je l'ai désinstallé ai redémarré mon ordinateur puis depuis Creative Cloud téléchargé à nouveau Photoshop cc2025 et réinstallé.
RIEN n'Y fait c'est pareil !
Aurais-je dû le réinstaller sans mes préférences mais Pffff, je suis épuisé avec ces manipulations !
Grrrrr !
Merci a ceux qui pourront nous aider !

Another user here with over 25 years of experience: I can confirm, this has been happening for over a year. Everytime I encounter it, I consult the forums and still no fix that works. It's frustrating that such basic functions that built Adobe get ignored.

Sadly, if it's not AI related, Adobe could care less and wont fix it.

Polygonal lasso BACKSPACE or ESCAPE no longer do what they have been doing since... forever. This is totally breaking the functionality of the tool. QA much?
