To some extend X11 is treated as a step child on Mac OS X.

I get the same error with line 1468:

    fpgApplication.netlayer.WindowAddProtocol(FWinHandle, xapplication.xia_wm_delete_window);

commenting out this, i get the error on 1828

  XGetGeometry(xapplication.display, TfpgX11Window(awin).FWinHandle, @rw, @x, @y, @w, @h, @bw, @d);

where I stopped.

when asking on the darwin mailing list, i received this answer:

   Explicit XSync or XInterAtom() to make sure the messages don't pass, queued in the night, and then you try an operation on an object which was queued but not serviced.

     You can see if sync is what's required by turning it on using the server option, so that you get it on every request, whether you want it or not.  Documentation on how to do this for Mac OS X's X11 server is at <http://developer.apple.com>.

This does not tell me much, but I'll search around. Maybe, it tells you more than me.
