I have a Vista SP1 installed on a Lenovo laptop. The touchpad has, to the right, a emulator of a scroll wheel of a regular mouse. It used to work fine but now it stopped working. I did a lot of updates and installed a lot of software (office software and security software recommended on this site) in between, dunno if there is a connection. Tried reinstalling the driver, but that didn't help.
any ideas what the problem might be?
Thanks,
Shushi.
