Tablets :: Cursor Disappear When Switch From One Windows Account To Another

I've got a problem with my cursor disappearing when I switch from one Windows account to another. The older account got set up this past Christmas when I got the computer and the newer one got set up a couple of weeks ago. I had no problem with either account until today: now, suddenly, I'm finding that when I switch to the newer account, the cursor just flat-out disappears and doesn't come back for love or money. This leaves me unable to do very much of anything except switch back to the older account, where my cursor usually reappears. But as soon as I go back to the newer account, I've lost the cursor and can't make it come back.

For months now, I've been frustrated by the apparent oversensivity of the gesture interpretation on the touchpad. I innocently move a finger along the touchpad to get it from A to B and find that it gets interpreted as a wish to scroll or bring up a context menu or whatever. So yesterday, I disabled all but the single-finger gestures. The problem seems to have begun right after that. After various reboots and other experiments to get my cursor back on the newer account, I finally decided to re-enable the gestures as they had been on the theory that perhaps that was causing my cursor problems.

Any way to keep my cursor from disappearing in the second Windows account? And if you know how to keep the touchpad from reacting to every minute movement and interpreting it is an attempted-gesture when it is just me moving my hand.

The laptop is an ASUS K55N, which was new at 2012.
