I have a Dell Studio with Vista.Because my cursor was jumping to other email pages and skipping back into my text I had tried unchecking the "hide pointer while typing" under pointer options/mouse, and it did not solve the problem. Download Touchfreeze. It is a small Google code sofeware that will solve the problem. And do donate. It is worth $5 to have this headache really go away!
