Windows 7: Missing keystrokes in online foms - IE8?

Hello,

Something is causing a delay in my keystrokes being logged by online forms in IE8. I type at a very fast speed, so I notice when my keystrokes get lost. I can type all day in Word, and Outlook, and even OneNote, and not lose a single keystroke. However, when I am completing forms online, there seems to be something between me and the form completion that is not fast enough to catch all of my keystrokes.

The only toolbars I have in IE8 are the Google toolbar, and the McAfee toolbar, and these have never caused this before. I have recently restored my system from an image backup, but I was experiencing this before I did that, today.

Can anyone give me some clues as to why this may be happening? It certainly is annoying me because I have to go back and type my words after I know that I have already typed them completely.

Help, please! Thanks!
