Query: Not so hot for desktops

The mouse worked great (and feels great) at first, but quickly started glitching and locking up. After a bit of experimenting the problem seems to be that the mouse has to be less than a foot or so from the USB transmitter to work reliably. Not a problem for laptops, but my desktop is on the floor and the mouse is unusable.
