I use hot corners to activate Exposé but for some reason they're not working a lot of the time now. I'll chuck the mouse into a corner but nothing happens. A restart brings them back to the way they should be, but logging out and back in again doesn't.
This has only been happening recently, but I can't think of what's changed. Has anyone else seen this?
Searched for this but turned nothing up - hopefully I'm not running over old ground.
