In the mouse settings, there will be a Symantics tab for the trackpad setup. The default configuration is set up for 2 finger scrolling (which still doesn't seem to work very well) AND 1 finger scrollign along the right edge of the trackpad.
The 1 finger scrolling works MUCH better than the 2 finger scrolling does. So I just use the 1 finger scrolling now and life is much easier!
so what's wrong with 2 finger scrolling? I have some observations. I am comparing it to my 6 year old Apple G4 ibook, which handles 2 finger scrolling perfectly 100% of the time.
The apple will scroll a web page with 2 fingers as long as the web page is the primary window no matter where the cursor pointer is. I think that's how most people expect it to work. So if your pointer ends up off to the side and not on the web page, it still scrolls. If your cursor is in a drop down text box it still scrolls. If your cursor is on the browser header area (File, Edit, View, etc) it still scrolls. Also, Apple allows for the 2 fingers to be more out of line. ie, the 2 fingers do not have to be in a perfect horizontal line on the trackpad. Look at your hand, fingers 1 and 2 are different legnths, they aren't going to line up horizontally unless you make an effort to do so.
The Lenovo and Synaptics driver will not allow 2 finger scrolling if the cursor pointer is not in the web page body. So if you are off the web page, or on the header, or in a dropdown box it doesn't scroll. Also, if your fingers aren't nearly perferctly in line horizontally it wont scroll. Your longer middle finger does not naturally fall into a horizontal line with your shorter index finger and the trackpad doesn't recognize your 2 finger scroll request.
It seems like Lenovo and Synaptics should pick up a 6 year old Apple notebook at a garage sale for 10 bucks and reverse engineer the trackpad. Most other manufacturers have figured it out!
