Hi,
I am a newbie to linux as well as modelica.Each time i try to simulate a model on OMEdit I get the following message.I was trying to simulate a thyristor circuit given in the examples.

(OMEdit:4394): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed (OMEdit:4394): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed

and the  screen hangs ,as in the image. Can someone please tell me what is wrong?
