Synaptics two-finger-tap right-click happens on non-tap

view story

http://unix.stackexchange.com – Pardon the horrendous title, I'm not exactly sure how to summarize the issue I'm having. Basically, I have synaptics, and I right-click by tapping two fingers on the touchpad because my touchpad doesn't have any buttons. This is great, but I get all sorts of extra right-clicks because unlike left-clicking (tapping with a single finger), the right-click doesn't require the contact to be brief. Left-click (single-finger) requires the tap to be a tap, i.e. if I put a finger on the touchpad, leave it there for a moment, and then raise it, it is not a click. That's great.
