I have been having problems with my Screen saver and Alt-Tab for a few days now. I am not using wireless mouse or keyboard, and have been mainly using my touchpad on my laptop rather than hooking up my USB mouse. The problem that I am having is that my screen saver will not turn on, and alt-tab only stays on screen for about a second and a half before vanishing, leaving me no real time to switch between tasks if I have more than two tasks running at once. I am pretty sure that this is somehow tied to a problem with my touchpad, though I am not positive. My conclusion that it is tied to my touchpad stems from the fact that when I open Windows Live Messenger, the "Find a Contact of Phone Number" text box automatically gets a blinking cursor. Has anybody else had this problem and fixed it successfully? I was told that it would require a complete fresh install of Windows, however I do not want to go through the trouble of backing up the 70GB of information that is stored on my computer if I don't have to.
