I have a laptop with a synaptics touchpad running on win7 x64.

When i use the scrolling region of the touchpad in some applications, for example in Visual Studio 2008, Notepad and Windows Media Player 12, the scroll is very slow.

If i pull the edge of the touchpad slowly the program will scroll one row at a time(regardless of the number of lines-settings in the mouse configuration). If i pull the edge quickly though, the program will instantly jump like 20 rows making it way too fast.

In some applications, like Firefox, the scrolling work as expected.

Changing the scrollspeed-setting for the touchpad does not help. If you make it slower it doesn't do the 20-row jump but then it's horribly slow and if you try to make it faster it will do the jumps all the time.

I have tried both synaptics generic drivers and the "special" drivers that HP provides but they both have the same problem (except that the generic one can't adjust the scrolling speed, even though that didn't help anyway). With windows generic drivers the scrolling region doesn't even work. Other mice i've tried with scrollwheel work as they should do.
