Hello there,
I don't think this will help you, but it won't do any harm.
I have had a similar problem but only when using 3D applications. The problem i had was with Anti-Aliasing and Direct Draw, the drivers weren't rendering the pointers properly.
My first port of call to fix the problem would be:
- Testing directx by typing "dxdiag" on the run menu, see if everything is displayed properly
- update directx & graphics hardware drivers (if there is a problem)
- turning down the appearance settings to see if that helps
I'm think about more ideas.
Good luck ,
Chris
