Right.....
I have a Acer Travelmate C320 Tablet (XP) connected to a monitor with USB Keyboard and Mouse attached.
Every time i close the monitor the use the laptop in a desktop fashion, the mouse wanders around and sits about 3 inches down and 3 from the right of the screen, each time you move the mouse it goes back to this point. Open the lid and it works fine, close the lid, problem persists.
I have tied putting a piece of paper over the touchpad in case its that, but it doesnt seem to be as i have the touchpad icon in the taskbar which shows if it is being used, and it isnt.
Confused.....Help?
