I have a VAIO VPCM120AL running W7 Home Premium, today I experimented 3 times that the touchpad was going crazy, the first time I was just searching for something in my files and the other 2 happened when I was playing an online game (League of Legends): while trying to move the cursor, it stays n the same place on the screen while the movement seems to activate key shortcuts and combinations, sudenly various programs open up like the calculator, widows help, internet, windows explorer, the desktop turns (left, right, upside down) so I have no option rather than turn off the equipment and restart all. I already run AVG and SUPERAntiSpyware but couldn't find any worm or troyan. Thanks in advance for the help.
Thanks for all the information, but I changed to the previous version of the controller and the problem seemed to be fixed. Anyways I will save the pages that you provided me for future problems. Thanks.
