3D crashes... and sound doesn't work in Abuse-SDL
 

I have two "major" problems, so I decided, instead of posting two threads, of making one for both ;)

1) Sometimes I have to use MESAGL (for example, for Armagetron or TORCS), and one third of the time the PC hangs. It starts the program, and then just hangs, without displaying any message error. This happens everytime I access the same program twice in a row, and some other time at random. My 3D card is an ATI Radeon 9250 AGP, what can I do?

2) In Abuse-SDL, I can't hear sound, why? I don't have any problems at all when I play Armagetron or TORCS...
