Ok. Lets say when I open the notepad application and keep typing in something or leave the application idle for about 1 min, the click occurs at the "File" Menu and the File menu opens up (Noticed: The cursor does not move to the "File" menu) or I would say "ALT" button was clicked. I have not had this problem on Windows XP.
I am also looking into the other processes that can cause this problem.
Pl note: This is a DELL laptop, connected to external keyboard and mouse.
