This is an issue, to varying degrees, with all Adobe apps. I use a M1 Max laptop with two additional montiors. Whenever I switch up monitors (home/work/Cintiq), I have to reset the Workspace, as Adobe does a poor (non-existent) job of remembering how I had it set up last with that permutation of monitors.
Cutting to the chase, in this case, I can't drag the palettes over from being halfway off the monitor back into view. I've tried turning off the Graphics Processor. I've tried resetting the Workspace.
I can drag each palette individually into view, but not the whole group.
Thanks!
It's quite frustrating having such a seemingly basic user interface issue!
