Failed entry of keystrokes

[[email protected]]

When I type in on-line forms or e-mails; when I type on my machine's log in screen; when I type on Word or in other apps my keystrokes are not always entered. I adjusted the delay rate and that seems to have helped. Except that does not seem to be the action that should be used to fix the problem.
