Problem with Cross references in online and Printed output

[Mohinda]

I have cross references in most of my help topics for online help and for the PDF output. They work fine in both outputs except one cross reference. In the online output, this cross reference displays as the whole topic underlined instead of the heading. In the PDF output it shows that it should link to page 1. When I hover the cursor over the cross reference, the link broken symbol is displayed. I have checked the path using Edit Cross refrence menu and it seems to be fine.
Does any one know what's causing this behaviour and how to fix it?

I'd open that topic in the Internal Text Editor and review the xref code. I have had problems where editing regular content near an xref has screwed up the xref or the text, and I've seen two xrefs next to each other but only one visible in the XML Editor but both appearing when I build the output. I had to look at the code to figure out what was going on.

Thanks, Lisa.
I will examine the code for xref with internal text editor.
