I've run into a bizarre situation every time my MacPro first starts up in the morning when I get to work and the screen saver activates for the first time. When I try to deactivate the screen saver hitting the keyboard or mouse nothing will happen. At best I will get one of the following...

Able to move the mouse but clicking does nothing
Login prompt will show up but typing on the keyboard does nothing

At worst the screen will be fully locked. In all cases I will have to reboot my machine to get it to work again. After this initial restart the machine is fine for the rest of the day.

Anyone encountered something like this before?
