Thanks for this detective work Gary.  We've been discussing how to  
manage errors lately and have come up with a consistent story...  But  
for now you are correct I have to address the issue where the wizard  
simply shows no layers available.   It should give feedback as to  
what is going on.  Not a simple problem but critical for a user.
