Problem: It is double clicking when I do a single click in Windows 7. It is quite annoying as it open up programs even when you select it or close programs. First did virus and spyware, malware scan to make sure the computer is not infected with this crazzy little programs that cause your computer to go mad.
Then as advised in the Troubleshoot mouse double clicking when you do a single click, installed the latest version of Intellipoint software.
Now mouse seems to work normal.
