Hello,

I've been using the V560 laser mouse for the past year and I've had problems with it recently.

It will be working fine one second, and then suddenly I'll be unable to move it from side to side, it only moves vertically. If I tap my mouse gently on the desk it fixes itself temporarily, but I don't want to have to bang my mouse on my desk to fix it.

What might the problem be?

I noticed that there is a firmware ugprade (1.1, I'm currently using version 1.0) but when I downloaded and extracted the .rar file I was unable to run the file.
