close window with python curses module

[Nicolai Ehemann]

I have a python application which uses curses. Now and then, I'd like
to open dialog boxes for user input, which are closed after that. As
they should appear on different locations of the screen and with
different sizes, i don't want to use the same window object for all of
them. So, is there a way to destruct a curses window object, or do you
have any other suggestions for this problem?
