My tablet can't detect touch event on my flash app

I am trying to create an application that supports multitouch, My flash app running well on my other gadgets are asus vivobook and sony xperia SL, but the Acer Iconia W700 Windows 8, do not detect touchevent. This tablet can detect 10 touch point in ms.paint. Touch is considered as a mouse click, so it can not run my multitouch flash app.

Is  any other software that is not installed, or an error in exporting?

to try, I've uploaded a sample touch/mouse event detector. http://www.4shared.com/document/6Ya3bqOl/mouseortouch.html touch on blue box, if it goes well, it will display the words "touch detected" not "mouse detected".

what about your tablet? Thanks Before
