I randomly hit something or something strange happen in Leopard.
I toggled a screen where in MS Vista you can choose between opened windows in a 3D environment basically it stacks the windows so that you switch between them and see there contents.
Does anybody know how I did this? Is it just a fluke that it happened at all?

Also didn't know where to put this because I didn't see anything for Leopard only the newer ones. So if there is a place please move it to where it needs to go and sorry for posting in the wrong place.
