goto with external document

[Matthew Baker <Matthew.Baker@gmd.de>]

Hi,

I'm trying to make a PDF file (actually a collection of linked PDF files)
idiot-proof.  I have a top-level PDF file with links to others.  When you
click on the others, they close themselves (\goto{....}[CloseDocument]).
The trouble is, if the user doesn't have Acrobat set up to open links in
separate windows, the top level document disappears because it's already
been replaced by the other document.  Anyway around this?  Can you make a
\goto go to the previous view if it is the only open window and close the
document otherwise?  Or something similar?  I can't provide two buttons
because the linked-to document only contains one thing: an image.

Of course, the user can click on the back arrow instead of clicking on the
document but that requires a bit of brain and I can't guarrantee the users
would have that unfortunately.

- Matthew
