Move a window back into the visible area in Xubuntu?

On my laptop, after I use a higher-resolution external monitor, applications will sometimes place themselves outside the visible area of my desktop. How do I move them back into the visible area? (No part of the window is visible, so I can't use the mouse.)

I'm running Xubuntu 9.10 (XFCE)

Solution 1:

Found it, I'm answering just in case someone else get confused.

Under: settings -> Window manager -> Keyboard

There is shortcut called "Move window"

And if I first cykle the app into focus with Alt+tab and then Alt+F7 (the move window), the app jumps to the mouse pointer and then I could just place it where I wanted it..
