Any times I log off vendetta, computer crash and need to reboot
What's hell.
What's up ?
My conf : power pc dual core 2ghz OS 10.4.8
NVIDIA GeForce 6600LE
Thanks if you have got a idea on what's happening?

When did the problem start happening? After a Vendetta or some other software update? After a change in hardware?

You might want to peek in your error log immediately after the reboot and see if there's anything interesting.

The problem is, I don't play to Vendetta since I changed computer and monitor.
If I'm in window mode when playing and quit, Vendetta dont crash.
I have a 20 pouces (apple monitor) and nothing in error log.
