Popping up dialog boxes come to mind. At the very least, the Dialog
class would need to have obtained a capability on the top-level Morph in
order to position a dialog box centered on it.

Thanks for the explanation on the rules of safe globals. Helps a lot.

Is it time for a Squeak-E mailing list already? Or aren't we boring the
general readership here to death?
