Lee,
We test constantly on Win98 and were seeing some problems that sound
exactly like what you describe. Updating to Elsa's latest driver for the
GeForce 256 appears to have cleared up the problems (was surprised that
NVidia's latest Generic Detonator 3 driver exhibited the problem). For
now our problem seems to have gone away.
