Mousepad problem on the Windows side

While logged into Windows XP using bootcamp, the extreme left corner of the mousepad is not responsive - I have to click about 1" from the far left to make it react. The right side is fine however....and everything works fine on the OS side as well. Any suggestions?

Only on Windows? I know one of the options in bootcamp is to set a corner as a right click - but if it doesn't do anything I don't know. What happens if you mess with the right click setting?

One other thing - and this is only another guess - but it is worth a try - When I am in OSX - every now and then my 3 finger gestures go south and stop working. The only way I know to fix it is to create a new user, log out, log in - and it comes back. So if messing with the right click settings doesn't do anything - why not try making a new user on the windows side and see if it works with the user.
