Thanks for letting ius know Bill. I can't say I am surprised though as these Micro$oft keyboards seem to be at the bottom of several problems recently although I used one for many years and was very keen on it.
I'd like to replace it but it just wont die. I even have a spare one just like it. Besides what PS2 keyboards are still available as I hate USB ones.
My MS Intellimouse optical mouse is going on the blink, left mouse button is getting flaky. Thing must be 6-7 years old. That's a lot of clicking!
BTW what problems have MS keyboards caused?
