I've just been reading the "kernel panic"-thread and thought about how often I had to restart in the last year. Not often, to tell you the truth. 4 or 5 kernel panics, that was it.
But what bothers me more, is that there are some programs, that don't cause a kernel panic, but sometimes force you to reboot anyway because they take over the entire processor time.
And one of the most unexpected apps there was - for me - preview.app. It happens about two or three times a month, that i try to open a few jpgs - and in opening them, preview just about freezes, but not totally (you can i.e. move the mouse pointer a few centimeters in a few minutes, but most of the time you get the beachball, or just a frozen pointer. finder clock stopps, too). And then you have no other option but to restart. Obviously not processor time left for escape pod to work, too.
does this happen to anyone else with preview?
