Description Rick Moseley 2008-06-24 13:37:34 UTC

After opening more than one source window and then trying to close one a
stacktrace occurs:

There appears to be a problem with the SourceWindowFactory class.  It does not
appear to handle multiple source windows properly because when one closes it has
no clue about which one closed.  Seems some smarts need to be added so it knows
which source window has been closed and it can clean up properly after it.
