We have indexed our Public folders and a few Fileservers. Not using
Categories etc. for the moment.
I have a problem when the Search webpart returns more than one page
of documents in the Matching Documents webpart.
I can see the 200+ (or whatever) as well as the Next and Previous
choices.

But when I click Next I get a blank screen with the Search webpart.
So I never get a chance to see the rest of the Best Match.

I have renamed the buttons in the panel, but apart from that I do not
think that I have modified the webparts.
