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.
