Random log outs when playing Armagetron

[Matt Modica]

For some reason, whenever I play Armagetron Advanced (an OpenGL 3D Tron Game), 
I randomly get logged out after awhile. I don't get an error message, I just 
get taken to the log in screen. It does this every time I play. I also notice 
that if I play and then exit the game, it will log me out eventually even 
though I quit the game. Many times, the screen will turn black and it will 
show text for a split second (I can't read it unfortunatley) and then log me 
out. And one time, it froze for about 10 seconds and then logged me out.

It works fine on all my other games, including SuperTux, TuxPuck, Pinball, 
Pingus, EnemyLines3, Starfighter, Airstrike, KETM, KBall, and KQ. This seems 
very odd. I am using the XFree86 driver on a SiS card on my Acer Aspire 3000. 
I am running it on medium settings at 1024 x 768 (I can post exactly what 
they are if necessary) and am getting 30 - 45 FPS. The game itself runs fine, 
it occasionally "hiccups", but it is no big deal. Its the fact that it just 
suddenly terminates that is very annoying. 

I ran with the command 'armagetron > armagetron.log 2>&1' so it would make a 
log file, but when it logged me out and I looked at the log file, it was 
empty. I would greatly appreciate any suggestions and help to resolve this, 
as it is one of my favorite games. Thanks in advance!
