When I hit F11, this is what happens. It's been happening since 10.3.6, and Expose is slow and blocky when used in this way, and has also caused a handful of serious crashes when used. Anyone have any idea what the problem could be? Thanks 8)
I know of a hack which allows you to change Expose to the described behavior. Did you install some new software that lets you access system preferences not yet available directly through the GUI? Or did you enter a terminal command?
