Touchpad "Tap to click" misbehaves badly

The tap-to-click function misbehaves really badly for me (xf86-input-synaptics). It is mainly 2 problems:

When I move my mousepointer short periods of time (doesnt seem to go by distance, but it is in the range of 16px-64px depending on how fast I move) and then lift my finger of the touchpad, it reponds as a click.

When I tap-to-click on something that needs precision(a 8x8 button) I notice my pointer moves away alot, causing misclicks and irritation.

I am certain both of these are fixable (even if it requires some C-coding), since I get none of these problems in Windows 7.

PS. My touchpad has a really shitty design (you have to click on the touchpad itself really hard to press the mouse buttons) which makes "tap-to-click" pretty much obligatory.
