Hmm... If you can save, then the UI must not be actually hanging
(which would be a deadlock problem, probably). I suspect it's a problem
with an infinite loop. What is your model doing? Is it a DE model?
DE has a "feature" that if an actor fails to consume input tokens that
are present, the actor is refired at the current time. If it continues
to fail to consume the token, an infinite execution where time does
not advance results...
