I assume this refers to an already fixed bug, when customizing a panel was way to easy, and users dragged tool occasionally instead of clicking...
Does it still happen for you?

I'm looking into other options. Sketch I guess? I already have it but never thought I'd consider switching. Obviously Adobe developers and the folks making decisions about UI and the toolbar are not interested in the customers who actually use the software. This is so sad and frustrating.

The new bar is awful. The suggestion to switch to the advanced one is redundant as it already on that setting my problems are:

why are the add/minus anchor point under the selection tool and not under the pen tool.

why are the square tool with the shaper, pencil etc tools? And ellipse tool with the eraser etc tools? why aren't they with the other shape making tools?

why is the pen tool with the type tools?

Who made this toolbar?! why were these tools randomly grouped like this? it makes zero sense!

Adobe- If it ain't broke don't fix it. It was fine. You messed with. Now it is a mess. Just change it back the way it was before you messed it up.

I use Adobe Illustrator a minimum of 40 hours a week and I am typically able to adapt to any update provided by adobe fairly quickly. However, I have been using the latest tool bar update for months now and there is no getting used to it. I have to reset my tool bar every hour or so due to the tools moving positions on there own. I find my self searching for tools more often than not and have yet to find pattern in which I am able to understand it. Pure frustration.
I have been using this software for years and have yet to have this much trouble with it until the recent update. Please revert back to the prior toolbar settings.

Thank god I'm not the only one. I never had a problem with the old one. Now I find myself switching back and forth between basic and advanced and it's driving me crazy.

I also hate this new toolbar. Between this and PS, I feel like Adobe has made a mess of their UI. I'm not sure who they're asking, but every designer I know thinks it's horrible.

This toolbar 'modification' is simply change for change's sake and only brings frustration to users. "If it ain't broke, don't fix it" - please make this into a sticker and put it on your software developers' machines ... and in the next upgrade make it an option to lock the toolbar ... for those that do not enjoy the perpetual hunt for the right tools.

thank you

I hate the new toolbar. Things keep getting moved for me as well.

THIS IS NOT RESOLVED, YOU DON'T UNDERSTAND THE PROBLEM!!!!!!

NOT resolved. Tools keep moving around. HUUUUUGE waste of time finding them buried within the tools of the toolbar. How does this happen???

Even if I add stuff to the "custom" toolbar it changed the regular advanced toolbar. This is creating so much wasted time. I am almost in tears. As suggested below the "advanced" toolbar does not revert to the original. It is continually effected by whether or not I change things in the "custom" toolbar. Please help!

You've stated this is resolved?
Tools still moving..................

This is far from resolved.

Be that as it may I still get tools moving of their own accord!
