I was trying to implement a feature that requires a tripple tap. It looks like Tablet Pro looses the third tap when "2nd tap and hold" is set to "Drag".
How to reproduce.Open the page below in Google Chrome or Microsoft Edge:
https://jsfiddle.net/14rgj8oh/Tap three times on the green area. With Tablet Pro disabled the text in the green area will display "mousedown 3".
When running Tablet Pro 2.0.0.4 on Windows 10 (Version 1511) in fullscreen mode with the following settings:
Single tap: Click
Long touch: R-Click
Double tap: (greyed out)
2nd tap and hold: Drag
the third tap will not be registered. You need to tap four times to get the counter to three. When "2nd tap and hold" is set to none the third tap is registered and the counter will work correctly again.
