Some of you may know the keynote reboot bug, the one where your computer reboots instantly instead of playing your presentation. This morning, I had the same problem (again), but this time, after rebooting my hot corners didn't work any more, moving the mouse to the corner no longer called in expose or dashboard. It turned out my preferences were reset to none, so I didn't have a hard time resetting it to my personal preference, but I find it very odd this has happened. Did anyone else experience this? With or withouth keynote crashing?
