I guess you're probably right .... call me old-fashioned, but WhyTF would anyone want their PDF document to be able to do that ? I can't over-emphasize what a Bad Idea that seems to be. Adobe must be insane. "Lets get all our users accustomed to the sight of Acrobat Reader providing links in PDF documents which can be clicked to cause network connections to be made to remote destinations ... that'll help." I suppose a personal firewall would show the initiating software to be the associated client, rather than Acrobat - not sure that's any comfort tho. As somebody pointed out to me off-list, the setting for these URI features is "3" which appears to mean disabled ... but I'd still like to see the code ripped out and obliterated.
