The Acrobat JavaScript Reference states that this function requires Reader Save Rights to work in Reader."
I enabled user rights and the 'Save as' window still does not open when the user clicks on a button.
What can I do?
I now have Acrobat 8.0 Pro.
Security was increased in Acrobat 7 and several functions that used to work in a document context were changed to privileged. The "doc.saveAs" function is one of those. I'm pretty sure that this means it will work in Reader, but only from a privileged context.
