That is honestly something I have not experienced.
Did it work before you up installed the touch pad driver
Have you checked all the setting making sure something funky didn't get clicked, by the ghost of vistas past?
Have you ran windows updates, after installing the drivers
Have you tried uninstalling the driver then running win updates?
Are you getting tired of my questions?
If yes, Im done
If no, I can make some more up for you :P
