Can't assign mouse button to 'desktop' in Exposé.
I've got a MS BT mouse and for more than a year I've had it set to click and right click on the button 1 & 2, button 3 (pressing scroll wheel) calls up Dashboard, button 4 (thumb button) is Exposé 'all windows' and button 5 (the other thumb button) was Exposé 'desktop'.
All of a sudden I can't assign any of the button to Exposé 'desktop'.
If I swap the assignments round I can use button 5 for dashboard or Exposé but assigning any button to Exposé 'desktop' doesn't work. the F11 key still works.
Any ideas? The only thing I can think of that's changed was the last security update.
