Um, stupid question, but how to I reset the default window size and position of Vista Media Center? I somehow managed to either re-size it or move it off of the reachable portion of the desktop. If I go non-maximized the window shrinks off up towards the top and disappears. If I try and select move or size it takes me to the top of the screen and shows the arrows to move and size, but I cannot find or move / size the window. Is there a way to reset the default window position?
