Adjust Palm Check Sensitivity On Mousepad?

I recently reinstalled Windows 7 on my laptop. Prior to formatting, the mouse was working PERFECTLY. After formatting, the mouse is acting much differently. I am using the Synaptics software just as I was before I reinstalled Windows 7, and the mouse pad is MUCH more sensitive than it used to be when my palm hits it. If I type anything in the QWERTY row, my palm never fails to tap the mousepad and it screws everything up (you know how it goes).

I've gone into the Synaptics settings and changed palm check sensitivity and everything else on there that I think would help, and nothing does.
