Whoops!  Zurgle users beware...the TeletypeWindow class isn't happy
with something after Zurgle is loaded into the image!

I get a rollback:
MessageNotUnderstood: contents:
in TeletypeWindow>>initialize

It appears to be the line:
	label contents: 'teletype'

in the initialize: method.

It works fine on an image without Zurgle...after I apply Zurgle, it stops
working.
