When I hit the Show All expose button (usually F11) my contact list flies off the screen.
It didn’t used to do this, and people have stated that it is to do with incompatibility with Apple Spaces in Leopard, but the messages window still stays on the desktop like they both used to.

How come I can make my messages window stick to the desktop properly but not my contact list?
(I am on Leopard by the way)
