Hello:

  I have a Mu script that draws some text using openGL (gltext.writeAt()) and it appears on the monitor but not on the presentation device.  Do you have any documentation or examples of how to do that?  Is it even possible?  We are using Rv 4.0.9 in linux.  Thanks!

  Hi Jake,

  You will want to make sure to set your custom mode's internal variable _drawOnPresentation to true in the constructor. That should do the trick. Please let us know if that does not work.

  FYI the same is true of Python modules (self._drawOnPresentation = True).

  Thanks,
  Jon
