Over the past few months, I have had this really odd effect happening with my computer mouse. Every few days it will start shuddering. Reinstalling the driver or just re-booting may sometimes but not always sort it out. Sometimes it will just come and go. When it comes through it becomes difficult to click with my mouse. I have just rebooted to get the service tag for my machine and this time it has gone.

Any help to get rid of this will be welcome.

Thx
