Thanks for the response. Since your post, I have been paying more attention to where my fingers are when things get whacky. I think typing slower makes the keyboard input more consistent. So, probably part of the time, I am touching the mouse pad with my thumb. OOPS!!! Where is the touchpad disabling in Windows 7?
That said, the mouse pad is still giving me fits and the keyboard seems to still occasionally have an attitude. Any other ideas?
