When I load that here I see only a single button, which does nothing 
when I click.  I do not see any graphic, nor any means of navigating to 
other cards.

I don't know, but that won't stop me from guessing. :)

My hunch would be that using both the copy and paste commands would not 
work, because IIRC the HTML export runtime does not currently work with 
the system's clipboard.

That said, using the copy option which lets you specify a destination, e.g.:

   copy grc "cricle" to cd 2

...may work because that method doesn't affect the system clipboard.
