Animated Masks? (with feathered edges)

I’m wondering if anyone can help me. I’m setting up an interface, and some content boxes are slowly revealed by a mask once the animation runs. I decided I didn’t want just straight lines, so went to edit the Movie Clip with mask applied. I basically have a rectangle which expands and reveals the entire content area. Only, when I edited the shape (which is grouped in the mc’s timeline) to add a stroke and the hand-drawn stroke style, but when I preview it, the edge of the mask is as straight as ever. Is there a good way to create a mask with uneven edges? Also, on the subject of feathered masks, how are they done? Is it just a matter of a mask and a layer over that with a gradient on it (which gives the illusion of being part of the mask)?

EDIT: Here’s a quote which confirmed my suspicions:

Flash ignores bitmaps, gradients, transparency, colors, and line styles in a mask layer. Any filled area is completely transparent in the mask; any nonfilled area is opaque.

Hope someone can help :beam:,
