Progress is being made, apparently

Browse Source 
curses/curses_misc.py:
  Made Dialog a bit more generic with the new Dialog2, also supports mouse events.
  Included TextDialog and InputDialog as subclasses of Dialog2
curses/netentry_curses.py:
  Changed error() to support Dialog2
  Added support for mouse events
curses/prefs_curses.py:
  Added support for mouse events
curses/wicd-curses.py:
  Added support for wicd's hidden wireless-network functionality
  (Really) finished refactoring for the changes in ComboBox
  Made some transitions a bit more immediate by calling update_ui() manually
  Refactored to about_dialog to support Dialog2
  Added support for mouse events (clicking to select, mostly)
  Added support for retaining current list netlist focus throughout screen updates
  (Hopefully) Added support for handling an instance of 0 available wireless
    networks
in/man=wicd-curses.8.in: Hidden network support is fully functional
man/wicd-client.1: Added a word. (You'll live.)
setup.py: From last commit: Added the python "shebang" to the top of the file
