Well, I spoke too soon, and my happiness with turning off the inertial movement thing didn't last long, and that setting didn't help much. However! I did get a lot more relief from turning off something called "Fast Initialization" in the mouse settings. Changing this setting also decreased the number of tabs and options available in the mouse settings control panel, so now I can't tell you where the inertial movement option was. I suggest you skip to opton B, below, but if you want to keep hunting for inertial movement, I *think* it was here:
Option A: Inertial movement (maybe): Control Panel-->Mouse-->Pointer Settings tab. I also turned off "Enhance Pointer Precision" there. If Inertial movement is not on that tab, look for the tab that has a mock up of the touchpad with yellow right angles in each of the corners--I think it may have been there.
But here's the better solution (although it won't get you the touchpad of your dreams, unfortunately, or I should say, the touchpad we paid for):
Option B: Turn off Fast Initialization:
Control Panel-->Mouse-->Hardware tab-->click on Alps touchpad in Hardware tab->Properties-->Advanced Properties Tab. In that window, make sure Fast Initialization is *not* checked. You might also use the Help button (?) to get advice on increasing or decreasing the other two options. I now have mine set to 200 sample length and buffer rate of 300. OK your way out of there. I think you may have to restart after this, but Windows will tell you.
I hope this helps! Please post if you find something even better!
