I have a Dell Vostro 1000 and am having touchpad "tapping" issues.  I just spent about an hour on Dell chat and we downloaded lots of stuff that should have made the driver issue o.k.  However, while it seemed to partially resolve the matter, I still am having very frustrating issues making the tapping of the touchpad work.  I have to R-click below the touchpad to engage on the screen.  Since we have all new drivers, etc., installed, could this be an actual physical touchpad issue?  Could the ability to receive/send the tap message  be lost?
