Mouse problems after resolution change

[WetWired]

I installed the game just fine, and even at the default resolution, which I THINK was 800x600 everything worked fine. I went into my options and set my resolution to use the same as my desktop, which is what is recommended for this monitor, and now my mouse is stuck in the upper left hand corner and will not move. I can't get to the options to try a different resolution. Anyone got any ideas?

I'm using Ubuntu 8.10 ibex and gnome.

go into your .frictionalgames directory in you home directory.
and remove the "settings.cfg" file in the sub-directories there (depending on which game you are running)
