I have a cordless logitech keyboard. One thing I discovered was that whilst typing either on or off line, the Logitech page would suddenly open up. Try as I might I was unable to discover what combination of keys was doing it. In the end I emailed Logitech for advice. I never heard back from them. In the end I had to disable the quick touch keys and it seems to have solved the immediate problem. However I now feel the web,mail and search keys are useless to me. If I re-enable them, I have to put up with a web page that opens up at random, seemingly. The cordless facility is fine, but as it never leaves the desk have noticed little advantage to it. The cordless mouse that came with it as a package is a real boon, no messy cable getting in the way.
