My new stuff does this too. Here's why:

When you switch away from a page, the morphs on the background get deleted and 
held in the CardPlayer's privateMorphs collection.

And when Connectors get deleted (or when what they're connected to gets gc'd) 
they disconnect themselves.

I think if I were doing it, I'd probably consider keeping the PasteUpMorph 
around (or moving all the morphs into a private container temporarily).

Actually, a better solution might just be to use removeMorphs: which is 
provided by Andreas' MorphRemoval changeset. It lets you remove morphs 
without deletion.

Anyway, Scott may be able to shed some light on this.
