Hi ! I have bought a wireless keyboard and mouse, installed both, and the keyboard works fine but the mouse doesn't respond at all. I have tried everything suggested in the operating instructions, to no avail, but wonder if there may be some conflict between my original mouse and this new one. I have uninstalled the new keyboard and mouse, and gone back to my old configuration, which works fine (I know, you're wondering why I bothered buying a wireless set, aren't you - so am I now !) SO... I wonder if I ought to uninstall the old mouse before trying to re-instal the new one again, but I'm loathe to do that as I can't see how I will then be able to access everything I need to re-install the new outfit. I'd be very grateful for any advice as this is causing a lot of GRRRRRRRR!!!!!! I am using Windows XP Home Edition. Thanks for reading this. Eunice Cubbage
