My computer has recently developed a very strange problem (it is a 3 year old HP). When it is first turned on, or activated from stand-by mode, a single click on an icon (usually outlook or internet explorer) launches that piece of software 30, 40, or 50 times before I can stop it--usually by hitting escape or end. This has just started. I ran a virus scan and nothing showed up, and I am at a loss.
Any helpful ideas would be appreciated on how to fix this problem.
