This appears to be the latest on the "tap-to-click" issue:
We very appreciate your comments.
According to “tap-to-click” issue, our technical support team is working on it and will add “disable” function into driver and absolutely release soon.
Another “scrolling” issue, our scrolling design is limited by Synaptics’ Patent, so we develop another technology on it.
We suggest that when you are using scrolling function, you can just hold your finger there until reaching the desired destination.
If you have other comments, please kindly let us know.
Thanks.
Yours Sincerely,
Sentelic Corp.
Seems like it's going to be fixed.
