Here's one workaround I discovered this afternoon:

  on newGraphic
    lock messages
    copy last grc to grp "contents"
    delete last grc
    unlock messages
    select last grc of grp "contents"
    pass newGraphic
  end newGraphic

It' still imperfect, as it lets the user draw the object initially on top of
the scrollbars.  But it moves into the group so quickly that it's a livable
annoyance.

Any other solutions?

Also:  Is there a way to interactively edit points of a polygon graphic?
