Occasionally when I select an objects bounding box node to resize it, the cursor will not let go. When I release my finger off of the mouse it does not deselect the bounding box node. I am very confused as to why this is happening. I've been using Illustrator for over 15 years and never had this happen. 🤷🏽:female_sign:
In the past when i've had issues like this in illustrator.. just strange UI quirks that don't make much sense and don't happen entirely predictably or reliably... it's almost always been some third party software running on my computer that caused the issue. For a few months a couple years back i had routine issues with Illustrator's UI while Google Chrome was also running... A tremendous pain as i use both constantly.. Eventually the issue went away, either with a fix from adobe or a fix from google.. i'm not sure which..
Anyway.. Long story short.. Try to identify any other apps that are running that might be interferring.
Try closing EVERYTHING except for illustrator and see if the problem persists. If it goes away... then open all the apps you normally use and see if the issue comes back.. If it does... Systematically close one of those other apps at a time and see if the issue changes or goes away.
