same thing over here (Touch pad not stable) ; Sony Vaio VPCEH3QFX; intel core i5; RAM 4GB; windows 7 Home 64bit; Thanx
My Viao trackpad works most of the time, but I do get the same issues as the previous posters. It behaves in a somewhat erratic way sometimes, an external mouse works, so I usually just switch to that if the trackpad starts playing up. It's not just on the internet either, can happen anytime. I think part of it is to do with static in my fingers and/or moisture. Usually wiping my fingers on a towel or removing the charge from my fingers does the trick. Trackpad too sensitive I think.
