Tired of really having to mash the trackpad bar on your Eee PC? You're probably making the same mistake I did of thinking that it only has one button and trying to press it in the middle. However, it actually has two: one on the left end, and one on the right. If you push the center of the bar, you're really trying to press both buttons at the same time.

This seems obvious in retrospect but it wasn't mentioned anywhere in the manual or other documentation.
