Weird gameplay in Win2k, lockups in Win98, plz help!

OK heres the full story. I bought this game 1 week ago. I was very excited to see all the nice 3D and graphic specs. But when I finally installed the game and started it everything looked really weird. At the Shiny splash screen the music stopped and the picture started to fade back and forward. It continued to do that until I pressed the Esc button. It took me to the games menu where the same thing happend. I managed to start Tutorial 1 but after a few seconds of playing the game started to behave really weird. This is kinda hard to describe and I have never had these kind of problems before in a game. The background (the sky) started to move up and down, jumping you might say. And then my wizard started to "fly" over the map. The whole picture started to jump and my navigation map was spinning around. When I pressed on of the arrow buttons the navigation map stoped spinning. But as soon as I tried to move my wizard to a location he started to fly over the map again (not the navigation map but on the landscape). All the polys were also taking new shapes (trees and stuff moved when I got close to them). I started to read the troubleshooting guide and see if it had any answers. I upgraded my drivers but it didnt help. So I started to read topics in this forum. I tried some stuff like disabling fogging etc, but nothing helped. Note that this happend when my comp was running under Win2000Prof. My comp has the following hardware:

OS: Windows 2000 Prof
CPU: PIII 650 MHz
Disp adapter: Hercules 3D Prophet SE with the latest drivers for Win2k V6.34 (GeForce256 Chipset)
DirectX: 7.0a
Sound Card: Sound Blaster PCI128

Later on I gave up and changed OS to Win98. Then the game started to work just fine except one thing. Everytime I surrender I get a black screen and the comp locks. Nothing helps at this point except the reset button. In Win98 I use the latest display adapter drivers for Win98 V6.35 and DirectX 7.0a.

So here I am with a great game that doesnt work under Win2k or Win98 (Note that I didnt change OS entirely, I now use a dual boot system between Win2k and Win98).

If someone have any suggestions on what might be wrong I would be very thankfull. It would be even better if someone from the Shiny crew could help me.

Thanks

Oh I forgot to write that my display adapter has an onboard memory of 32 MB.

I have exactly the same problem, can't run it under win2k and can't lose or surrender in win 98. the only workaround i've found to avoid rebooting is to alt-f4 at the defeat screen then restart the game
