I just tried MM7 on my other, newly upgraded machine (AMD Athlon/Nvidia Geforce2mx) and had the exact same problem-- flip right back to desktop. On both machines, I can run the game in soft mode, but not with the hardware support. I can't figure it out b/c other people have had no problem with MM7 and w2k, directx8, and a variety of systems. If it had just been my 3dfx system, okay, but now I feel like i'm jinxed or something. Anyway, all my other games are rockin on w2k, so maybe i'll just play mm7 on my win98 laptop, where it's perfectly happy. (but i'm still going nuts with this mystery)
