Hi, I just posted (and ccd you) my setup on another thread. Please let
me know if you have questions.

Thank youu verrry much !

I run on a headless server, so I don't have personal experience with a
desktop installation, but I don't believe the limitation you describe
actually exists.

 

Please try the setup that I posted. I think you will find that it allows
you to do this.

George, thank you so  much for this suggestion, I hadn't considered this would have been possible.

Does the manual mention this anywhere ?

Otherwise the hypotetical footage would suggest this out of the blue and that could be disorienting to someone who is learning.

But it's a very nifty trick !

Thanks !
