I have a Dell Studio XPS laptop, and I recently formatted the hard drive and reinstalled Windows 7 with the provided CD, and I can not get two-finger scrolling to work.  I have done a format/reinstall before with no issues, but this time, I am having issues.  The option to enable it is not available when going into the Mouse menu from the Control Panel and into the Dell Touchpad menu.

I downloaded the Synaptics driver from the Synaptics website, and there is an option to enable it through that, and it is checked, but it does not seem to make any difference at all.

Any help would be much appreciated.

Thanks
