One of my users is utilizing an HP Laptop 6510b with Windows XP Pro Sp3
Intermittently when she logs in, the Mouse cursor will start skipping all over the screen. I have tried uninstalling the driver for it and letting Windows use the default driver for this device and it has not resolved the issue. I downloaded the latest driver from the manufacturer's web site and its actually and earlier version than what I took off. I've little faith that this resolved the issue. It is a Synaptics touch pad.
What might cause this, and how might I resolve it?
