Adonay,

Glad to hear you have solved the issue :-D

The problem you give of the window disappearing or not appearing at
all is because the variable 'other' (or a,b,c) goes out of scope when
the _init_ method returns. You need to keep a reference to the window
object (which your new code does by using the global windowList). You
could also have defined the object as 'self.other' which would have
the same effect (although without a window list).

Regards,
Chris.
