I have just bought a used Gateway lt2022u netbook. It has WINDOWS XP on it. I bought a wireless mouse but when I try to install it (I assume the software is in the USB plug), I get a warning that continuing with the installation may cause system instability now or in the future. It strongly recommends NOT installing it. This is a standard off the shelf wireless mouse. I also tried another wireless mouse from another computer. It works fine with the other computer (also with WINDOWS XP) but I get the same warning when I plug in the wireless connector into the netbook?? I don't want to mess up the netbook so I am using it without a mouse for right now. Any suggestions??
