[texhax] Latex question

[Mel Janowitz]

Gentlemen:

   I am a current TUG member with email address meljan at optonline.net.
I have not been able to figure out how to cross-reference figures that
involve pictures I have created. I can cross-reference anything else I
want. It occurred to me that perhaps I am making a mistake creating the
pictures. I boiled it down to the essentials and am attaching a sample
file. I tried this on three separate latex systems.

Thanks,

Mel Janowitz
