// I was once able to produce a situation where the corresponding configTaskPane was removed from
// customTaskPanes in the background, and when we came here, it crashed. The pane was visible in the window that was closed
// and was reused in a new window I created. So in order to avoid crashing in this strange
// situation let's catch the exception.
// The only way I can think of handlicng this cleanly would be with a window closing event, but I did not find out how to
// get it (in word)...
// I could also try to work on open events, but there is no window open event
// Note that the Document.Close event does not fire at all in case of multiple windows on the same document
// which is exactly the problem I am trying to address...
