Wx internal error, means that the driver tries to send a message to a
non existing process, the demo could probably be improved there.
That ERROR should be a warning, I don't want remove the message
completely since it can help the developer.

Gtk warnings, I can't do much about them try starting firefox from the
shell most gui programs on linux have but normally they go to
/dev/null, they can depend on half implemented gtk/gnome themes and
wxWidgets internal problems/hacks.
