I didn't check the example nlp_3.py (from openopt) regularly. So I can't tell you when it stopped. As a workaround I have used another backend in my matplotlibrc #### CONFIGURATION BEGINS HERE # the default backend; one of GTK GTKAgg GTKCairo FltkAgg QtAgg TkAgg # Agg Cairo GD GDK Paint PS PDF SVG Template #backend : WXAgg backend : TkAgg Cheers, Nils ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
