Bonjour,

Quand j'utilise l'Outil Correcteur Localisé en cliquant avec ma souris sur une zone de la photo à l’écran, une multitude de lignes partent dans tous les sens. Donc cet outil ne fonctionne plus depuis plusieurs jours. Est-ce un bug ?

I was having the same issues with multiple tools in Photoshop. Finally after a day of trying all things, we have found a solution on Reddit. I tried it and it fixed it right up. This is for PC only.

Create a text document with Notepad. Name it “PSUserConfig.txt”
Write “UseSystemStylus 0” in the text body (that’s a zero not an “O”)
Save it in “C:\Users\*YOUR USER NAME*\AppData\Roaming\Adobe\Adobe Photoshop 2026\Adobe Photoshop 2026 Settings

(In step 3, *YOUR USER NAME* is unique to whatever your username is.)

Restart photoshop and the tools should work again.

Credit to u/Professional_Use442 on Reddit for sharing this fix. Note: If you want to use the stylus again you’ll have to follow their instructions on how to re--enable the stylus mode.

Is there a fix to this? My lasso & clone tools aren’t choosing areas I want.

Hi its me again, after reviewing how i did the solution pinned in the main post, i noticed that my text file was named “PSUserConfig.txt.txt”, so dont be dumb like me and be careful to NOT write the extension in the name of the file
Seems like its working now, THANKS BYE

@kklarson13 there’s a thread here that may be related to your issue

It could be an assortment of reasons -- dirty mouseball (if present); battery low on a wireless mouse.

After the first click, does everything between clicks “connect,” that is, as TVO says something is keeping the eraser stuck in the on position (like, the Shift key)?

I’ve seen this happen when your shift key is stuck. Easiest thing to try is unplug your keyboard and see if the eraser tool does the same thing.

I click once and it erratically draws eraser lines all over. Sometimes it will stop after the first click and work normally again, but I can't go back and undo the random erasing without the problem starting all over again. Working on PC with a mouse.

This is making photoshop completely unusable.

Do you use the mouse or do you use a graphic tablet?

Please provide a copy of your 'System Info'. This can be get from the Photoshop menu item Help > System Info. There's a copy button in the System Info dialog. Press this button and paste the info into a text file and attach it to your next forum post.
