Anyone else experiencing this strange phenomenon?
I open some PDF documents, then leave the computer for a few hours. When I come back, they have all been resized to only show the title bar AND they have been pushed off the bottom left corner of my screen, so that only a tiny portion of the title bar can be seen. I then drag them all back up into view, and resize them so I can read them again. Give it another couple hours of not being actively used, and they disappear back down to the corner.
Very strange Abobe... what's happening?
