I have had my Logitech MX 510 for about 2years, it great, and i love it, but over the last few weeks it started behaving rather oddey, every now and then it shoots the curser up/down the lenght of the screen, for no apprent reason. i've google these symtoms, but all i can find it people who are trying to use it on plain white melomane or simular surfaces it cant hack. But i have always used this mouse mat, and other that geting a little grubbyer than it did, its still the same mat!
-What should i do, should i try and get a replacement or what?
