Multi-Touch in Silverlight - doesn't recognizes the touch point

Question

I'm having this Silverlight project which I'm working on. I'm currently trying to add Multi-Touch functionality to it, and I'm having difficulties. It seems like the system doesn't recognizes the touch point immediately when I'm touching down on a point, but only when I'm releasing it. This affects the map control I have - its not supporting pan, and the zoom doesn't work properly. I suspect that this might be because of a Context Menu on Right Click that I use (to be specific, it's Telerik's RadContextMenu). Can anybody tell me what is wrong or what is interfering the Multi-Touch behavior?

Answer 1

Maybe you're setting the windowless param to:

<param name="windowless" value="true" />

Apparently multi-touch functionality doesn't work when using this setting, along with other things:

Sadly, it looks like all of the official documentations doesn't mention the multi-touch functionality limitations.
