Today I had my first system lockup.

I first started realizing something was wrong when my MacBook would no longer enter sleep mode when I moved my cursor to the upper left (as I setup in Expose ). I figured I messed something up so I initially was not too concerned. Later in the day I went to turn on the bluetooth radio - no joy here either. This is when I realized something was very wrong. Time to shutdown and restart - the only problem is that I could not shutdown either. I checked for hanging applications, applications running amuck, the usual suspects  - nothing. I finally had to restore to the old Windows style of holding down the power button.

After restarting everything seemed to be just fine. But this early in the game for a total lockup is troubling - especially when I am still using my Windows based laptop for more hours during the day than my Mac.
