I'm having problems with my wireless mouse --- it was working find untilt he other day. My laptop recognizes the mouse but the mouse does not work. I've replaced the batteries and tried reinstalling. The same thing always happens, it installs, recognizes the mouse but doens't actually work. Has this happened to anyone? Also, has anyone installed Limewire on their mac? Had problems or viruses? Should I buy and/or download a virus scan program? Is it worth it or are there really no viruses for macs? Thank you!
