Did it work OK before on this computer and O/S?. If so, what has recently changed on your computer (new video driver, whatever?).

If you have only recently changed to Windows 8 then have you followed the instructions for installing the game under vista/seven or later as pinned in the sticky message at the top of the forum? - specifically, it should not be installed under /program files/.. post Windows Vista due to Microsoft's UAC.

Also - have you tried playing with the scroll speed variable on the MISC tab of the GameOptions launcher programme?.

Cheers
