I searched it on google and kind of had a feeling it was because I was using dual monitors. This is what I found - https://discussions.apple.com/thread/3766438 Is there any way to fix it? When I try and go on a different screen once my mac is unhooked to my other monitor, I'm not able to drag the pp back on my screen. The only way to fix this problem is by opening display preferences and changing the screen size. Is there another way to keep it from doing this without having the open display preferences? I take my mac to class everyday and opening pp everyday like this gets pretty annoying..
