Google TOUCHFREEZE and see if that helps.

There are times as i am typing a post or email, the screen either disappears or gets smaller. I suspect that i am hitting something on the touch pad as sensitive as it is, that makes it do it. Or is it the 64 bit mode that is doing it? In the interim, I am using my wireless mouse to better effect with it. As far as that touch pad...i tried to see what all the functions are and some work and others nothing seems to happen.
