My fallout 2 crashes rabdomly with the application error message i cannot read. It crashes when i am inside an inventory, in battle etc. The first sign that a crash is imminent is a strange mouse cursor: the mouse cursor won't change it's appearance even though i enter or exit battle mode, or it would show two cursors superimposed. However, this thing doesn't always happen before a crash, sometimes the crash is unexpected.
I have FO2 human-gus installation + killap 's patch, encounter booster, the patch that makes chars show the armor they are wearing and the ammo patch. However, this kind of crash occured with any combination of the above patches and with no patch present.
