are you sure you bought a MAC version of the game?

[/QUOTE]
No, I'm running the Windows version on my MacBook(Intel version running MacOSX) using Wineskin which provides a Windows environment so to speak. The game itself runs fine, as does JSGME, MultiShex, and SHKeymapper. But I can't get the mission editor to run because something is missing in Wineskin I think. If I knew what the editor uses I could probably add it using Winetricks, which provide dlls, VB runtime, etc.
