That 'crash' would
really bother me (being a perfectionist).
Hope ya get it fixed eventually.
As an IT professional, the fact that it exists bothers me too - but since it only is on one PC and I estimate it would take me 20-hours-with-luck to track it down, I can live with it. Particularly since there are some excellent ways of avoiding it, such as:
1. Always start the simulation in windowed mode (from the desktop icon), never in fullscreen mode.
2. (If Jim isn't listening) just use it as a ScreenSaver.
