I was going to suggest that, but felt it might be too obvious. In my new laptop, occasionally it essentially locks the control key as down, so I can't type in emails. I've googled and googled to find out what the problem is and evidentially, according to lots of posts in various discussion forums, it is usually its an add-on mouse and its driver.
So it MIGHT be a similar problem. But I definitely would try checking the Task Manager first. HTH, Marnie In a message dated 12/14/2012 2:27:11 P.M.

The one thing that I'm sure is common to every occurrence is I go to move the mouse pointer & find it's frozen.
