Hi Folks.

I just tried to create a new SystemWindowWithButton from the Morphic "Add a
New Morph" menu (under "Windows") and got the following walkback:
"UndefinedObjects are not indexable".

My Platform:  Win NT 4.0, SP 3 running a baseline Squeak 2.4 w/ all of the
updates (up to 1155)

Analysis:  A quick look at the walkback seems to indicate that the
SystemWindowWithButton label is nil and something is asking nil for its
size.

This is probably due to the recent size method changes.
