Remove Two Finger Tap response from AIR Desktop

Hello there,

I'm currently develop a Kiosk project and I encountered with Two Fingers Tap problem.
My entire app is using Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
BUT when I publish it as AIR 26.0 for Desktop and tested it on Kiosk Touchscreen,
there's a weird square appeared for a second when 2 points touched at the same time across the screen or one point is pressing and another point just tap.
It looks like when we press and hold on folder to right click, but this happened with two fingers tap instead of press and hold.

My app can't be interacted when this happened.

I've tried remove 'press and hold as right click' from windows 10 touch setting but it's still there in AIR only.
None of other programs on windows react to two fingers tap like this.

Could you please help? I'll post more photo when I get to the touchscreen again.

Update 1: I recorded the effect I talked about.
And I've made small script for GESTURE mode and test with the same touchscreen.
It appeared that on the GESTURE mode, nothing happened when I 'two fingers tap' like in the video.
the question is, How can I block 'two fingers tap' event from TOUCH_POINT mode.

Thank you in advance,
Warut
