My Windows 7 install has a strange problem where sometimes the scroll wheel icon for the mouse gets stuck on the screen.
It's hard to explain in words, so here's a picture (it's in the blank space on the right side, halfway down the screen).

Click start button > Type "Mouse". Now go to the pointer tab , Click on the arrow under "Schemes" and apply "Windows Aero(System Scheme)". Finally uncheck the box in front of "allow themes to change mouse pointer" .
This should work for you.
