Hi
I've just discovered wxMathPlot :)
I'm using Ubuntu 11.04 and eclipse as IDE.
I've a problem: after building one of the saples (the build end correctly), in the execution apper these errors

(prova wxwidgets:6634): GLib-GObject-WARNING **: cannot register existing type `GtkPizza'

(prova wxwidgets:6634): GLib-GObject-CRITICAL **: g_object_new: assertion `G_TYPE_IS_OBJECT (object_type)' failed

(prova wxwidgets:6634): Gtk-CRITICAL **: IA__gtk_container_set_border_width: assertion `GTK_IS_CONTAINER (container)' failed

(prova wxwidgets:6634): Gtk-CRITICAL **: IA__gtk_container_add: assertion `GTK_IS_WIDGET (widget)' failed

can someone help me?
(the hello world of wxwidgets works correctly so it should be a problem related to the wxMathPlot)

thank you very much :)
