Sorry I haven't replied lately. The last 2 days I have endeavored to learn more about NAGI in general, and I have to tell you Nick - It's awesome! (if you had any concerns about NAGI having legality issues - I'm sure Sierra is more worried about games being pirated than a bunch of fans hacking and improving upon their 15 year old interpreters, as long as it's not with their Half-Life engine, that is!)
Chris:
I have the latest version of DirectX installed (Version 8.1 I think, I do know it's the XP version). I tried your idea about removing the line with DirectX, and I AM SUCCESSFUL at getting NAGI to work!

The flip side is that NAGI won't work with DG or Naturette 2.
So, I'm stuck with my original problem, which is how do I work the mouse? NAGI seems to be not registering my mouse commands at all, but in all other respects it works perfectly (Windows 2000 still doesn't like it though; Windows hangs whenever I try to close NAGI).
Robin, I was able to get your game running once in English with the Sierra interpreter. It looks great.. but I still have a hard time getting around. Must be me, I guess.
Thanks again all!
Adam
