Hi Ian
I have this game it is the original from 1998, I just recently retrieved it from my collection of games and installed it on my XP machine even though it is windows 95-98 it played flawlessly for over two hours, so not sure what the problem could be....but i couldn't believe it when it started without a hitch...
Looking on the web it looks like there may be a problem in config with this game running in compatability mode....but thats all i know...
