The page is generated by a Dreamweaver template on which other pages, which behave correctly, are also derived.
It appears to me that this problem page has something to do with named anchors. As you can see in attached image, each letter of the alphabet will target the appropriate part of the site index.
This is on an intranet site, so I can't post a link. If needed, I'll be glad to post relevant sections of the code.
TIA
