[NTG-context] acrobat reader does not open a pdf

Hi everybody, Acrobat reader 7 (linux) cannot open "doc-test-gobck.pdf" I usually include external documentation (catalogs, etc.) as a clickable link which open another doc. ("parent-doc-test.{tex,pdf}" --> "doc-test-gobck.{tex,pdf}") On those external doc, I put buttons for returning to the parent doc. I was making this thru variables for easy creation, and moreover for multiple page inserting. But now (context version: 2007.04.17) acrobat (linux/ubuntu feisty & acrobat reader 8 win xp) refuse to work (kpdf does !) Have you a better approach (for making those "sons" docs)? TIA for any answer olivier Turlier PS: attached archive is too big, so I've put it here : http://profteb.free.fr/tools/context/pb-external-doc/
