Re: memory leak in gtk

["Michael Lamothe" <michael lamothe gmail com>]

I'm no master profiler but I think that you'll want to put a
gtk_widget_destroy(mainWindow); after the gtk_main();.  You really
don't need to do this because it will be destroyed when the
application terminates 0.01 seconds after that line.  But if you feel
you must then go for it.  I also like to tie-off loose ends.

Thanks,

Michael
