MOUSE_UP event does not fire when using a "wrapper" from other domain

programming flash

I added event listeners for stage’s mouse up, and everything works fine if I directly embed the SWF.

But if I use my partner’s wrapper to load that swf, the mouse up event doesn’t fire. I track the “stage” instance and it’s right there, just the event doesn’t fire.

The parameters our partner’s wrapper:

allowfullscreen: “true”,
allownetworking: “all”,
allowscriptaccess: “sameDomain”,

Our partner’s URL address:

www.domain-a.com/wrapper.swf

Our SWF’s URL address:

static.domain-a.com/movie.swf

Any tips? Thanks very much!
