[NTG-context] URL

Hi, I want to see active URL in my pdf document in similar way that is used by ....</a> tag in html So I have written \setupinteraction[state=start] then \useexternaldocument [doc:Molik] [http://zskl.zsk.p.lodz.pl/~morawski/local/Praca dyplomowa p. Molika.pdf] [Metody routingu unikastowego] then I try to use \from, \goto; \url and even if I see the link, it is not active then I try: \useURL [Molik] [http://zskl.zsk.p.lodz.pl/~morawski/local/Praca dyplomowa p. Molika.pdf] and \from, \goto; \url result is less or more the same. Where is the problem? What I have missed in documentation? Michal Morawski
