Yes, the about box was what I had in mind.  I hadn't even thought of 
scrollbars or menus; I'm not sure if there's much we can do there. But 
for dialogs opened with #showModal, we could (in theory, at least) keep 
running other Squeak processes while the dialog is up, if we were to 
replace the modal event loop with a loop driven from Squeak.
