I have not been able to replicate this, but I'm using the CVS tree, which has some deadlock fixed in PN.
It would be very helpful to have a stack trace. If you started vergil from the command line on Cygwin, you can get this by typing control-break.

I have been able to reproduce the (or a similar one)problem repeatedly. It seems that if during a simulation one hits the stop button on a vergil window that does not have focus, it causes vergil to hang in some sort of infinite loop. In this case, the status still says 'executing' (I am pretty sure that the other hangs showed 'execution complete' but perhaps I was wrong).
To see this problem, execute a long simulation with some sort of plot. During the simulation, give focus to the plot window. Now hit the stop button **without** first giving focus back to the vergil window. The simulation stops but the the status still says 'executing'. No further changes can be made to the model. Often times it is necessary to kill javaw (using the task manager) and restart vergil to resume normal functionality.
Hopefully this won't be too hard to fix.

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...
