My mouse has turned choppy and often doesn't work for a few seconds. I have been having challenges with skipping on You Tube. today it is skipping on medical transcription reports. I have Gateway GT5628 running Vista Home Premium. Had some fan noise and lubricated the ball bearing and that is solved. My foot pedal for the MT work often continues when I raise my foot. It stops when it feels like it. The sound is getting choppy there. I am running a McAfee scan as I write this. I tried to change the batteries in the mouse to no avail. I downloaded Fly Player add on for Mozilla Firefox. I ran Spybot and am clean there. Not sure what to do here. I am backed up with Carbonite so hopefully I have safe in that regard. Any help to be offered here? I sure appreciate it. I am a bit better than a novice but certainly no expert. I am just frustrated as I am having difficulty getting my work done today.
