Every program that creates a window in MS Windows is supposed to have a control menu. It's usually hidden, but can be accessed by clicking in the far upper-left corner of any window. Things on it are minimize, maximize, restore, etc.
Some programs don't have one of these. I would like someone to check to see if the Guild Wars 2 window has one. If so, can you make it pop up by clicking alt-spacebar?
My Guild Wars 2 window is off of my screens to the right. For any other program, I click alt-spacebar and it appears, even if I can't see it. Then I click M (to move) and hit arrow keys until it wanders onto the correct screen. But, Guild Wars isn't working.
