Microsoft Pandora's box bug / issue ??

[Siggy12]

Hello guys,
first of all congratulation for this fantastic emulator,
i want to submit a bug that I faced on this game "Microsoft Pandora's Box".
When you try to solve any "Focus point" puzzle, when you move the tiles game randomly exit to windows without show any error, this happen too on windows 98 but don't happen on windows 2000 SP4 (I'm talking always in PCem) for example
I can assure that this game work perfectly under windows 95 and windows 98 and this don't happen when you try other kind of puzzle but seems only related to the "FOCUS POINT" type.
