Ok...i've done a google search on this subject and can't find anything. I've had the same problem with photoshop, but in photoshop all you have to do is the "tab".
This happens all of the time and it's very annoying. When i have a document open and I want to minimize or move that window I can't because the top of the window is hidden behind the main menu. Why does it do this, I never dragged it up there? The tab key doesn't help.
