[Etoys] A bug in resize and undo

[Yoshiki Ohshima]

  Hello, (and Scott^^;)

  Abe-san found a bug in the latest OLPC image.  To reproduce:

  * Paint an object.
  * Add a script to the object.  (a "turn by" would do.)
  * Tick the script for a while.
  * Stop the script.
  * Resize the object with yellow handle.
  * Undo "resize Sketch" from the navigator.

And, if you tick the script again, it doesn't work.  The object seems
to be substituted by different one.
