Subject: [PATCH] Romulo:

-Solved bug 295
  + SelectedItemChangedInTree() event was called after the window had been closed and the object instance had been destroyed.
  + Horrible solution: added a static "destroyed" flag to indicate that the object instance has been destroyed.
    * Flag will be valid for all active instances, since it's static.
  + In desperate need of a better solution!
    * Need to find the correct location to put it, though.
