You shouldn't have that issue, even if using both a USB and a touchpad mouse
at the same time. (My question in my previous post was to see if your
touchpad was enabled. Apparently, it is.) Are you using a Vista compatible
touchpad driver? Your touchpad driver is active, even if you aren't
touching it. If the driver is a generic PS/2 driver from Microsoft, or is a
driver meant for XP, you may not have the functionality your laptop needs to
run correctly (look in Device Manager, under "Mice and other pointing
devices", to determine the driver). If you need help locating the download
for a Vista driver, post your computer make and model number, and someone
may be able to help you find it.
