Stopping a Window from loading twice.

[gstercken]

Second, it doesn't work anyway because when Window1 loads Window2 with the Show() method there is no way to know that Window2 has been closed. Unlike ShowDialog() Window1 is not notified when Wndow2 calls its Close() method.

Hm... But I still don't understand why you wouldn't simply handle the window's Closed event? That way, you can easily keep track of any window's state.
