Bug 185775

Description John Thomas 2007-05-07 10:53:13 EDT

You get an exception in MapView when 2 simulations are stopped together.
To reproduce the problem, start STEM and then start 2 simulations (I used Japan just because it is small and quick to start) Then use the Stop button on the toolbar within SimulationControl (it stops both simulations).  You should see the exception.
