Well I received my new G5 today from logitech as an RMA replacement, they sent me the blue version with 2 buttons. I had the rust effect version to begin with, before I had tracking issues with my steelseries s&s but I was able to fix it with a firmware upgrade. I'm having the same issue again with my new one, whenever I try to make quick movements it stutters and skips, I can't really find any information in regards to a firmware upgrade for this particular version. I'm also using Vista 64 bit, anyone else had similar issues or can offer any advice I would much appreciate it!
