Can't click-and-drag on Clickpad, and occasional freezes (Sentelic)

I have a Sentelic clickpad (no pysical buttons, i.e. macbook style). It uses synclient. I have upgraded to kernel 3.5.4-030504-generic on Ubuntu 12.04. Side or two-finger scrolling works. What doesn't work is clicking with one finger and a motion action with another finger, like clicking a window and dragging as one would commonly do on a touchpad. Also the touchpad occasionally becomes unresponsive, which can last a couple minutes before it randomly starts functioning again.

I have tried changing synclient ClickPad=1 and various other synclient settings to no avail. I paste my xinput and synclient output below. Any help or hints would be appreciated. Thanks!
