I just downloaded a demo and there are strange colour gfx glitches in it (software mode, possibly?). I'm really interested in buying the game but want to know if the GOG release works fine on Win7 x64.
(Sorry, I just realised I never posted this as a question!)

No graphical problems for me (Win 7) although curiously when I tried to run it in Win 98 compatibility mode I DID get graphical problems.

Thanks. Off to purchase now! :)
