after stop-ping a simulation run, we can still expand the simulation tree
|Status:||Closed||Start date:||16 Jun 2009|
in the normal way, by double-click-ing a tree-item that has not yet been unfolded, or using unfold menu item, or the right arrow button.
the animation is not updated, though - which is no surprise because when we click Stop to stop the simulation run, the reuse button in the animator becomes enabled, i.e. the connection to the animator is closed.
this should be fixed such that after Stopping a simulation run we can still navigate among the items already in the simulation tree, but we can no longer unfold (create new items).
