Hi Andreas:

I just tried your image+VM package out on NT 4.0...whenever I attempt
to save the image (WorldMenu->save) the entire VM locks up solid...no
response, requiring the task manager to kill.  I can save to a new image
name successfully, however.  This is directly from the Squeak startup
screen, flaps et al. enabled.
