I have Mac with OS X 10.6.6 running.
When the screensaver gets started and runs for a few minutes (10 or 15?) Thunderbind, Firefox and a few other programs gets terminated because OS X seems to want to log me out. This is very annoying as I have to restart all of these programs again and again.
The interesting part is I have another Mac also running OS X 10.6.6 where I do not experience this behaviour.
Any help is appreciated
