Forum: wxRuby help with clean exits

require 'wx'
require 'Eyes.rb'
require 'date.rb'

# I am trying to close then mainframe window cleanly so I don't have to
# shut down ruby1.9 via `kill -9 .....'.  When I press cancel on the 
first
# (welcome) window it does exit cleanly.  However when I try to shut 
down
# the main window using the close box, it hangs.  It doesn't even use 
the
# on_window_close window event.  How do I rectify this situation?  Any
# help would be appreciated.  If you want more info just ask.  Thanks
# Happy new year everyone!
