Dell Latitude E6430: Tapping on touchpad does not produce click

Hi all,

I'm running latest Windows 10 64bit on E6430. Few days before, tapping on the touchpad stopped working - no click is produced. Everything else is working perfectly. The driver is the latest one from Dell.

When I returned to an old driver which does not support multitouch, clicking works, but this way I miss the multitouch...

I guest that this has been broken with the latest Windows updates.

What should I do to get my touchpad fully functional?
