I have a user who uses a Dell Latitude D620 laptop with XP Pro. Randomly throughout the day the shift key just locks up even though it is not even being pressed down all the time. They are then unable to release the shift key from this state even though it is not pressed down. This affects all applications that uses the shift key - Excel tries to select a block of cells instead of a single cell and in Explorer when you press on 1 file/folder, it selects every thing from the 1st file/folder in the list. What would cause this and is there a quick way to relase it?
