Ok, I've got the MovieClip setup as a component, adding code to the
#initclip pragma to declare the class and link it to the ID in the
library properties page.

I've also added trace code throughout so I can see what's going on.
The constructor is called successfully, and I've created a method
called getQuestion that also is called correctly. However, within this
method I want to call a function declared on another layer as a
regular ActionScript function called downloadXml. The trace code
inside this downloadXml function is not called.

I'm guessing I'm probably overlooking something but I can't find
anything about what I need to do.

Thanks for any help,
Paul
