I have a NativeWindow that loads a swf with buttons. And these buttons are supposed to call functions in my "mainWindow" and vice versa the "mainWindow" needs to communicate with the NativeWindow. But how? First I don't know how to adress the "mainWindow" and second I get an error message when I try to adress a button in the NativeWindow ("winX") like this "winX.btn1" because this is understood as an unkown property of winX.

The swfs are both Flash CS4 and AS3 using document classes which is all quite new for me (obviously). Can anybody please explain the new concept to me!?

Thanks in advance!
