Some adjustments that can be made to help it work better are:
- Tapping - disable two finger tap for popup menu
This helps prevent the action of putting your thumb on the "left button" being mistaken as a two finger tap.
- Drag and Drop - disable to avoid dragging windows if you are fast, where you double-tap and move the cursor, and the Smart-Pad thinks you are dragging.
- Smart Detector - enabled, and change the detect area to where you actually put your finger.
You can tell after some moderate use by looking at the smartpad and seeing an area of "clean" (or grease - ewww). This is the area you most likely actually are putting your pointer finger.
However, if that's NOT enough, here's one more. It's a good one. Hack the registry. This will allow you to see all the functions the smart-pad software can control, but for whatever reason ASUS or Elantech disabled for the Zenbook
- Go to HKEY_CURRENT_USER\Software\Elantech\SmartPadDisplay, and change all values to "1"
- Go to the Elan Smart-Pad's properties by using the Mouse Properties dialog box
- Now you'll see all the hidden options
Once all the options are enabled, you'll see "Palm Tracking" under Additional tab. Turn that up one notch, and it'll make the smart pad less sensitive, but it also makes accidental brushing less likely to register as a mouse movement.
Interesting note on this. Once you make changes to whatever formerly hiddened options and click OK or Apply, the previously modified registry keys will revert back to the way "they want it". If you want to experiment, it's best to change all the values to 1's, export the registry key, and use that to change all the keys at once.
Not all the newly activated options will work with the Zenbook's Elan Smart-Pad, but the Palm Check is tested to work on my UX31. Hopefully this will help you get better control over your Zenbook.
