To whom it may concern, this is just to let you know of a problem that you may or may not be aware of? I found your site while looking for the answer to a huge problem I was having with my Microsoft wireless mouse and keyboard. I thought i had a hijacker. The mouse would freeze up and the only way it would work was to push the undo button. sometimes it would work for a few seconds or a few minutes.also the keyboard would not respond properly. Any way I happened to look at my receiver for the mouse and realized that when cleaning up my messs of wires at the back, that I had put the reciever on top of my dsl modem for lack of room. When i removed it to the floor all of my problems went away. No virus, hijaker,softwareissues.. Who new ? Anyway hope this helps Have a good one. Mike
