I find that the Windows key (the one between Control and Alt that pops up the Start menu) is both my best friend and my bane. It's my best friend because it's an easy way for me to get out of EQ. Usually the first time I use it in a gaming session it will minimize EQ directly, so I can do what I want. After that usually it will just make EQ a window that's almost the same size as my screen. For some reason the Alt-Shift-R doesn't work to give me mouse control, but if I can hit the Windows key again I get it, and then I can grab the top of the EQ window, move it a tiny bit, and then minimize it. I have to do it this way for some reason because if I try to minimize the window without moving it the screen basically freezes, although I can regain control by hitting the Windows key again. And then to get back to full screen I just have to hit Alt-Enter.
It's my bane because if I hit it in the middle of a fight, well, there can be a pretty long load time until I can do anything again, especially if it's the first time of the session. I don't do it very often, but it always happens when I'm in a hurry to get an important spell off.
Anyway, just some information for you.
Game on,
