I see this all the time and it's very frustrating. What's even more annoying is that most of the time, when I go to restore the window, it pops up on a completely different desktop than the one it was previously on (often not even the desktop I'm currently on). I want it to go right back to where it was when I restore. About half of the time it pops up on top of a full screen browser window and then the only way to move it back to a normal desktop is to quit and reopen.
