How do I create links between two pdfs using FrameMaker 9, while both files remain open?

In FrameMaker 9 is there a way to create cross reference to a particular page on another doc (without closing the current/source doc)?

I tried using "openpage filename:pagenumber" option, the link takes me to page 1 of the referenced doc not to the specified page, and as it is a hyper link when page 1 of the referenced doc gets displayed the souce doc closes.

When a link is clicked in the source doc, it is required that the source doc remians open.

This is an urgent requirement, can anyone please reply soon?
