The problem has occurred with both orders of installation. It is occurring now on a GeForceII card, but has also occurred on some voodoo cards.
I really thought this problem would be common knowledge and the position of Lucas Arts on it would be known.
BTW I have gold on all missions, I'm just trying to resurrect the game for my son to see if he can manange it
I may deinstall dx8, but certain things like the new 3dmark2001 require its installation.
