Hi. I have a Sony Vaio VGN-CS215J laptop. My laptop's touch pad mouse has been really buggy lately. Sometimes, the touchpad is working fine, but suddenly the touchpad wouldn't allow me to click with either the touchpad or the left clicker. Weirdly enough, even if this does happen, my right clicker on my touchpad usually works fine. It causes my scrolling to buggy sometimes too. I reinstalled my Synaptics driver for the touchpad and its still giving me the same troubles. My usb mouse works fine as far as I can tell. Is the problem most likely physical (ie. Do I have to physically clean out my laptop?).
