Greetings.

I recently rolled back from Win7 to WinXP on my gaming PC because I play old games almost exclusively. Suddenly Harbinger began to show nasty visual glitches (see attachments). I even can't leave the first location, because teleporter is not working. The green thing in the lower right corner is spinning (it's intended), giving from time to time ugly black forms.

Tinkering with DxWnd and D3D Windower does nothing. Compatibility mode does nothing.

On Win7 it ran flawlessly, strangely enough (only with WinXP compatibility checked).

Any thoughts, comments and advices would be appreciated.

Thanks in advance.
