Same view on initial opening or a return to home page.
Do you recall if anything changed since the last time you had home page content? Are all the usual items selected on the Customize menu? Are you working online and is Use Internet set to 'Yes'? Have you tried F5 to refresh the home page or Shift+F5 to delete the home page cache?
Please note what version of the beta you're using when reporting beta bugs. Especially since a new beta just came out today. Would be interesting to know whether Beta 4 broke something or whether you are still using Beta 3.
I've found the problem - related to testing for Bradley. I'd left internet off rather than on. Aren't you proud of how quickly and thoroughly you fixed the problem?
