Re: gtk_widget_show() not showing window

[James Scott Jr <skoona verizon net>]

Try this instead.  The gtk_widget_show_all() then gtk_widget_hide() then
gtk_widget_show() is the cause of your problem; unless you were thinking
the window should blink once before appearing.

James,

    #include <gtk/gtk.h>
