I have reached a point with this where it is impossible to go any further without the app. The issue does not appear to be related to Mono, as I am able to bring up the Tao OpenGL examples with no problem using VirtualGL and TurboVNC. I have created a tracker item here:
https://sourceforge.net/tracker/index.php?func=detail&aid=3300204&group_id=117509&atid=678327 Please post any further information there, so it will be easier to track.
