Ok, I know masking should be simple, but this is kind
of driving me nuts.
[Although, I'm nuts to begin with.]

I have [in layers back to front]:
a movieclip called "glow"
a movie clip named "gypsy"
a movie clip named "msk" < no a >
a movie clip named "trees"

So, I want to mask "gypsy" with "msk",
for an effect.

I used:
gypsy.setMask(msk);

And when played, "msk" and "gypsy" do not show.

["msk" is not supposed to show, but gypsy is supposed to
be revealed where "msk" is. And both don't show up.]
What's up with that???
