Photoshop CS problems.

I've been having problems with my Photoshop lately. When I minimize the window to do other things (homework), and I open the window again, I find all my graphics and icons have moved to the top of Photoshop, and I have no way of moving them down again. They are basically stuck at the top. I can't close the file or move it around. Is there anything I can do to fix it?

Edit: Got it. Thanks :)
