>>Are all these apps freezing often? Your problem may lie deeper than simply not being able to Force Quit. Keep Activity Monitor open and showing you All Processes. Which (if any) processes are red?<,
I've had my Mac Book Pro since last fall. It "crashes" loads more than I ever remember my Powerbook crashing.
I usually end up just powering down and doing a cold reboot. Today, and occasionally, the Mac is really hot underneath. It does that occasionally, but it still crashes even though it may not be hot.
