Have you tried #endEntry instead of #flush?

In the middle of the Morphic event loop, just after responding to events, and 
before doing other step methods and displaying the world.

Look for implementors of #addDeferredUIMessage:, look at the one in 
WorldState, look for senders of #deferredUIMessages, and you'll see 
WorldState>>runStepMethodsIn: which empties the queue.

And it's called from doOneCycleNowFor: which is  the body of the main Morphic 
event loop.
