My Synaptics Touchpad v7.4 won't move when I'm using my arrow keys. Everywhere I've looked on the internet is telling me to go to Device Pointer Properties Settings Pointing Sensitivity Palm Check and adjust those Palm Check settings, but that option isn't there and it isn't anywhere else. I've also read about going to something called "Smart Sense" but I didn't see that either. If someone could please help me, I would really appreciate it.
