Roaming user/Set bookmark as Home Page/Setting doesn't roam

I’m testing Notes/Domino Roaming user on multiuser Notes clients for a big installation project.

We have a specific database eg. START.NSF with frameset and all with links to all our databases in an outline. To set this db as Homepage works fine on our clients. This bookmark-setting (Set bookmark as Home Page) does not ROAM however even if bookmark.nsf is replicated nicely to the roaming server and replicated again to next machine when user logs on. The homepage setting is gone!!! WHY?

Is this a flag in bookmarks.nsf ???How can I do to make the setting roam?? PLEASE, advise asap. Regards, Katrin Dolk
