Won't shut down or reboot after Snow Leopard install

Ok it looks like i may have a new one. I have a Mac Pro desktop that has been running just great under Tiger, then Leopard and all the updates. Yesterday i "Upgraded"? to Snow Leopard and then the problems started. First Mail would no longer send messages, got that cured with custom port of 25.

Then i found that it will no longer shut down or reboot. Every time i try either it goes to a blue screen and the little round thing that goes round and round just keep going until you cut the power off. I have let it run for as long as 15 minutes before cutting the power.

It boots up fine and everything seems to work properly but simply refuses to shut down other than cutting power. I spent an hour on the phone with Apple and they couldn't figure it out either. Any one else run across this? or know of a fix?

Mac Pro, Mac OS X (10.6)

Same problem, here is how I fixed
1. Change any of the power management settings in system settings/energy saver
2. repair disk permissions through disk utilities applications/utilities/disk utilities/repair tab/repair permissions.
Done! restarts perfect now, Thanks for the help guys/girls whatever 🙂

note: if you are looking for the for-mentioned com.apple.powermanagement it (for me) was in mac hd/library/preferences/system configuration/com.apple.powermanagement. However I did not need to erase this.
