A User's Compaq laptop's cursor keeps jumping around screen while the user is typing.
The user uses the mouse track pad that is built into her laptop screen to navigate around her laptop screen.
This happens even though the option to automatically move the pointer to the default point in a dialog box is disabled.
Also the mouse pointer speed is set at the default setting in the very middle.
I have already updated the user's BIOS to the latest levels.
Also I have loaded all of the Windows 7 Home Premium updates.
What else can be done to fix this issue?
