From Dual Monitors to One - Can't see certain windows

So I used to have a dual monitor setup at home but then I took one of my monitors into work and then started up my comp at home and when I run PS it starts up fine and looks good up untill I try and bring up the Image Size window or anything like that. I believe PS is still trying to put it on my old monitor which isn't there which means I can't get to it to move it or close it and I'm basically stuck. I reset the Palette locations to the preset but that just moves the brushes and all that crap.

Anybody have any suggestions or am I just gonna have to uninstall and reinstall?

Tell Windows to just use one monitor in your display settings (uncheck Extend my Windows desktop onto this monitor).
