I wonder if the wxBufferedPaintDC crash happens on linux, I haven't seen a crash on windows but I know some of the windows api like GDI is forgiving of using released handles.
I'm going to try using wxPaintDC for non-win32 os, I notice this is used for ww_color_slider.erl so mac os and linux might already be double buffered.
