Windows 7: Bizarre Intermittent Typing Issue

I'm getting a bizarre off-and-on issue in Windows 7. Every now and again when posting here and elsewhere, my "S" key refuses to type...both on my Bluetooth and my wired PS/2 keyboard.
It only happens now and again - very weird if you ask me...and I know you aren't....LOL
I get around it by typing f instead of S and then using IESpell to correct it.
For this post I had to compose everything in Notepad first and then CCP. Next time it will most likely work.
Using IE8 by the way.

Comments anyone?

Do you have the same problem in notepad or just IE8? I'm using Firefox 3.0.4 and not having that prob. IE8 keeps being a pain for me. Hope they get it working right.

It was only in IE8. It started up this morning and then went away again...very strange.

Do you have any toolbars or anything in IE8? I'm running it bone stock and it's fine for me. There also might be something in the event viewer about a plug-in crash or something. You could try IE8 safemode and see if it improves, otherwise I'd say Firefox.

I did have Google Toolbar but it is disabled now and add-ons are the usual Java, Flash etc. and the only odd one would be IESpell but this problem started before I installed that.
I may have to make FF my default although I prefer IE for many things.

I've redone some of my more heavily used desktop shortcuts to open in Firefox anyway, so I'll see how that goes.

This is all going to self-destruct anyway in January I hear, so not too worried.
