Okay! A few months ago, I was having TROUBLE with my Logitech wireless keyboard. It's an older one that came in a set with a mouse, and a USB receiver that doesn't look like a USB flash drive (it's attached to the tower with a cord, and looks like a little quartered egg--if eggs were black and had buttons on them). The trouble was that I was getting extra characters when I was typing.

I talked with their SUPPORT extensively, and what finally fixed the problem was to set the keyboard to the default keyboard setting, as if it weren't a Logitech keyboard at all. The extra characters stopped appearing, but I lost the control function. It hasn't been too much of a problem; I've been able to use shift when selecting more than one file, but I foresee it becoming a problem in the near future.

Any ideas on how I can restore the control function without recreating the problem I had before?

OS: Windows XP HOME edition

I'm not sure what you need here, but if you need any more INFO, please let me know.
I have a unit much the same...
I unplugged the reciever and cleaned the front lens with eyeglass cleaner...
The issue went away.

Does your model allow for using different channels ? ?If so try a different one.
Another thing to check is cordless phones in close proximity...actually any electronic devices.Thanks for the advice. I did what you suggested, and still no control function. I have a cordless phone in the vicinity, but it's been there longer than the problem has.

I've tried to update the drivers, but when I do, I get the message that there's something missing from the logitech files. The Logitech site says that this particular model (Cordless Internet Pro) uses drivers that are already preloaded on the computer. I'm just at a loss here.

Do you or anyone else have any other suggestions?

One good thing that did happen is that I got my onscreen CAPSLOCK is on or off notification back. That was missing, too.
