I now have it setup with several links (actually, several loadpositions) within an article, which each open different articles in popup windows.
First class product & support.
I posted to their support forum 7 days ago, and emailed their support email addresses 3 times over the last week, but have received no help at all.
For a commercial product, I find the the complete absence of support unacceptable.
I am sure there are users for whom this just works OK - if so fine. But if you need support or help, then my experience is that you can forget it.
