I built a pc a few days ago. It has windows 7 ultimate 64 bit. Today when i started it and i clicked on start it also right clicked on its own. As i was typing in MS Word in the middle of a sentence when i clicked the space bar the pc acted as if i right clicked on my mouse. I ran CCleaner it did not help. I uninstalled the usb drivers for the keyboard and mouse using USBDeview that didnt help either. I uninstalled naturally dragon 11 because it was the last install i did before i noticed the problem but that didn't help either. Anyone have any ideas?
