I have a huge problem on BDroad1+2: Sometimes my screen turns black every few seconds on these maps. I have to press CTRL+ALT+DEL and the KDE-usersession-menu comes up where I press CANCEL. Then I can see and act for a very short time and screen flickers and turns black again and again and again. This really drives me mad

+ GeForce Ti 4200
+ latest Nvidia-driver (installed 2 weeks ago)
+ SuSE Linux 10.0
I'm a totally noob in gfx-cards... You are free to laugh now

or sending me a smoke signal.
The alternative .zip-file for BDroad that's recommended here in a different thread couldn't help me.
