Yeah, I tried it too.

Funny thing is, both Goodman and Shaffer assert that anything you can do
manually you can also do via a script (e.g. p431 Goodman), which was
probably what they were told when writing their books.

My theory is that HyperTalk was originally meant to emulate all user actions
in scripts, but that clicking or dragging with the polygon tool would
potentially hang the script if the start and end points were not the same.
So, this "feature" was silently dropped, meaning Yet Another Workaround for
The Rest of Us. (I shouldn't be too harsh, because I really love working
with HyperCard in general).
