Your version is working almost perfect.
Just a little detail: Why inertia isn't working on trackpad? I feel scrolling like old versions (without inertia).
Tested Release 4 RC3.zip and Release 4 RC4.zip and both are working well with trackstick and keyboard, but with the trackpad i'm experiencing a strange issue: it moves very slow and stops working for a few seconds while tracking.
What should I do?
Tested almost all versions, but just works the keyboard, but neither trackstick and trackpad aren't detected on Latitude 6430u.

Hope you could fix this issue...
Cheers!
