You don't need to be quite so drastic, fortunately.  Hypercard actually checks
and updates the screen condition quite frequently so it can pick up changes
as soon as you make them.  You can, for example, use the chooser to change
the screen and Hypercard will immediately adjust to the new screen settings.

It will also respond to changes made with FKeys such as Switch-A-Roo.
