There's nothing *wrong* Russ.  it's not a bug.  The script is
simply doing as it's told, e.g.

           .box b1 100 100 color=yellow fill=red

puts a bounding box on the screen, *then*,

            .put b1 pin=center scale=0%

changes it.  So,  you see the full size box, *before* it gets
changed.

It's up to you to neaten up the performance.   Do as you
would on a proper stage production, put out the lights,
put the cast in their places then bring up the lights.

.flash filename="box.swf"
           .box b1 100 100 color=yellow fill=red
           .frame 1
           .put b1 pin=center scale=0% alpha=0%
           .frame 2
           .change b1 alpha=200%
           .frame 100
           .change b1 pin=center scale=100%
           .frame 200
           .change b1 pin=center scale=0%
       .end

HTH.
