[Laszlo-dev] proposed workaround for swf9 context menu bug

[Henry Minsky]

Maybe if I make the bgcolor swatch be a child sprite instead of
drawing it on the main sprite, then
setting mouseEnabled won't cause views with bgcolors to eat mouse
clicks. According to the docs,
the 'mouseEnabled' flag only affects the mouse sensitivity of a
sprite, not it's children, and "mouseChildren"
is what controls the mouse sensitivity of the child sprites. I think
setting mouseChildren=false has already
solve the problem of turning off mouse events from child sprites which
hold assets.
