i have this problem with my new mouse. at the beginning it was perfect, but after a while it started to do this annoying thing - it moves only vertically.

i thiught it was an usb issue or something like that, but after many tests it seems its due to the device. anyone experienced the same issue and has some advice i didn't thougth about? i'd appreciate any kind of help. (don't want to spend again money for a new mouse - only if it's the only solution).
