Hi Jon,

I think I've setup my test correctly according to your instructions, however 
I'm still not able to reproduce your error.  

The original error reports that @@slms_tabs isn't in the current context.  So 
I wonder, what interfaces is this view registered for?  ISilvaObject, or 
something more specific like INewsViewer?

Cheers,
Andy
