I can’t seem to get the setMask to work on external swfs that are loaded into “container” movie clip.

However I got it to work with normal movie clips (not external)… so is there something I should know about masking an external swf? 😛 Any idea what I could be doing wrong?

And yes, I’m very new to flash 🙂
