Working with Vizard 2.14 on a computer running Windows 2000 and an ATI Radeon 9700 video card. I am having trouble loading a script in Vizard - it seems to get hung up after "adding" 11 VRML models. The black console window just stops printing lines and the rendering window is simply black. I can add the framerate to the top of the render window (using viz.framerate()), so it seems that the program has not completely frozen up... it just won't continue compiling code at some point.
