Thank you.

My problem is that I am using a custom external that places content
generated by the external in to the stack window (via the windowID of
the stack that I pass to the external). If I do export snapshot of stack
xxx, the content placed in the stack window by the external is not
recognized and included in the resulting image.

We may have to have the external modified to return an optional image
that we can place on a stack for printing.
