Same here, not as often as it used to happen, but more frequently lately it has been happening.
I am on 24.3, afraid to update and experience even more bugs.

Suffering this same bug on version 25.2.1 on mac.

@andikm I had this problem for a long time and it didn’t go away until I upgraded to Catalina. (Not sure which OS or which platform you’re using). Another bit of advice someone gave me that worked for me prior to the OS upgrade was to uncheck “Application Frame” and then recheck it, if I recall. (Window > Application Frame). Before discovering that, I usually had to restart the software. Hope that helps.

This is still an issue and now on Version 25.2. Not only on happening on Document tabs , but also other tabs such as Swatches, Brushes and Appearance.

Wow... while having opened one file, Illustrator 25.0.1 does not refresh the screen while opening a second document. Great Adobe!

Navigator switches the content, but the screen activates the second tab and shows the first file. clever...

Going to be fixed in early 2031?

Tyler: this is the first helpful info I've heard on this topic. Any other solution required restarting Illustrator (same for Photoshop). You're right, that does work. Sure, it's not a fix, but in the meantime, I'll take it.

To clarify: moving the entire application frame even just a hair to the right or left, then putting it back in place, does the trick WITHOUT a restart of the software.

I'm using 24.3 (have been for a while now) and still having the issue. Sorry! Wish I could say different!

Unfortunately I am still experiencing this problem when opening files. I still have to move the window around to get Illustrator to open the file. I have the latest version downloaded and am using the latest version of Apple OS.

rubbish. it is not fixed. i have the new updated Illustrator (24.3) and the issue has happened again. what does Adobe spend all our subscription money on? why is this not seen as important to get sorted?

Same issue here on my end, both Illustrator and Photoshop.. Has been an issue now for a year or more for me. Talked to reps in the forums, as did many others, they said it should be addressed 2 updates ago. Still an issue unfortunately. Not a massive problem rendering the software unusable or something, but at times, a serious inconvenience.

I am using Illustrator 24.2.3, Mac OS 10.13.6. iMac late 2015 (thus not the latest OS) 4 GHz Intel Core i7 / 32GB 1867 MGz DDR3 / AMD Radeon R9 M395 2048 MB.

Same issue here on my end. Has been around now for a year or more for me. Talked to reps in the forums, they said it should be addressed 2 updates ago. Still an issue unfortunately.

Sigh. I wish they would address this. It happens multiple times a day, and has other arbitrary behaviors occur once the main issue happens.

One more thing: Adobe Support, please note that this issue has been reported multiple times in different bug inquiries like this one. I believe this is due to this bug being difficult to name/describe. Therefore, when considering this bug for escalation/prioritization, please add up all of the inquiries on this topic which go by multiple names.

Thank you.

To the community:

Hey guys,

I'm perhaps reiterating what's been said already but the best workaround I have found is to move the Illustrator screen left or right. Just shifting it away from the spot it goes when clicking the full-screen button (which doesn't work with AI as it does with all(?) other apps on Mac, I might add), that enables the functionality to work again. Experiment with this to see what I mean.

To be clear, this does *not* fix the problem, but it gets around it until you are ready to restart AI. This, at least, has prevented me from losing work since I learned the trick.

To Adobe Support:
Please give this some attention. Bugs should not be measured in volume alone but also in severity. This issue is causing people to lose work. And, it's like sitting under a flickering light. It's grating on the nerves the user, causing ever-present thoughts of software alternatives. This is like sitting on a tack and eventually, those of us experiencing the issue are going to get up and find a new seat.

At the very least, will you please investigate and publish a do-it-yourself remedy to this? It was like pulling my own teeth out trying to troubleshoot this when I opened a support incident with Adobe. I had to repeatedly ask for the next troubleshooting step beyond the one I was being asked to try. "Contact us again after you've done this step and reference the incident ID." For reasons I do not understand, my support rep would not say anything beyond the current step when I asked until I eventually asked to speak with a lead or supervisor.

I would prefer to know the one step that fixes this issue for most/all users--but at least, I would like to know the steps I should follow without having to contact support after each one. The initial troubleshooting with support offered busyness but no improvement to the problem.

Support: in your internal notes from troubleshooting this issue with customers, which steps have resolved this specific issue? Can you share each solution that has worked? Will you please avoid sharing the generic answers, such as "reboot" and "delete your AI preferences file" unless you have records of these steps fixing *this* specific issue?

Thank you for taking the time to consider my request. I do like my Adobe products but this is driving me batty!

Can someone from Adobe please chime in on this? The problem has been happening for over a year for me and it is making me lose confidence in Adobe products. It happens to me on a daily basis, if I try to open a file that is somewhat large in size, the screen freezes and I have to move the window around, or change the window size to jostle Illustrator back to functioning and get it to open the file. What is the problem? and how will Adobe fix this?

I am having this problem right now and I've been experiencing it for years. I currently have 8 or so files open and out of nowhere illustrator will stop functioning and just freeze up. When I try to switch tabs, open a panel, menu, anything really, my screen does not budge even if I'm using keyboard shortcuts to tab over. The only thing that snaps illustrator out of it is if I manually change the size of the illustrator window by clicking on a corner and making it larger/smaller. As soon as I do that everything on my screen wakes up and works correctly until I need to view a different tab. Once I start having this issue (and it happens regularly, has been for years) I have to do the window resize trick every time I need to view a different doc. My only other option when in the middle of a huge project with several tabs going at once is to go one by one and save every open file and then quit illustrator and restart my computer. It is painful and depending on my patience level, that's usually when I quit working for the day because having to go through and reopen all my working files and set them back up after restarting my computer sends me into hysterics.

Not solved yet. I always have to close the program and open again. Very stressful when I have multiple files opened. This problem and the photoshop scratch disks combined are a nightmare.

Plz help!

same problem here 100%
any updates ?
thanks
