Question

AIR Desktop (win 10) touch event fires isTouchPointCanceled 99% of times.

I have an AIR app that used to work perfectly.

It is inconsistent, but after a Windows update (2nd january 2019) 99% of times a touchEnd event reports a: isTouchPointCanceled

As from Adobe docs: "Reports that this touch input sequence was canceled by the operating system. Touch events can be canceled for a variety of reasons, such as when a palm-generated touch is rejected because a pen stylus is in use. isTouchPointCanceled can only be true in a touchEnd event."

This is a windows machine with a touch screen for a kiosk presentation.

Is this happening only to me? This is driving me nuts and I have a deadline in a few days.

Touch screen application is not going to work on latest version of Windows 10.

Any suggestions?

Thank you

It also reports: touchIntent="pen"

When there is no pen attached, but it is a touch device:

"Reports whether the touch was generated by the primary or the eraser end of a stylus.

If a touch event is generated by a finger or other non-stylus input method, or a stylus for which high-frequency motion tracking is not supported, this property reports the value: TouchEventIntent.UNKNOWN."

So somehow Windows recognizes a touch event like a pen event.
