This is true because, >afik, all of the Logitech wireless devices use the same frequency. AFAIK they do NOT use the same frequency. These wirelless system have a number of frequencies programmed in, and select one at random. That is the way they make sure they're not interfering. This of course only works, if the number of possible frequencies is large enough, and the possible number of other system's that can potentially select the same frequency is limited. This 6 feet limitation is a design feature, to make sure of the latter. Anthony. -- Vragen over computer hardware?
