updated info...
The original control buttons stayed greyed out, so I just deleted them. After getting your questions, I thought I would add them back in to see what happens...
I added: Back, Next, Save, Edit, New, Delete.
Back and Next worked fine.
Save did not throw an error message on an existing record, so I assume it was OK
New gave me error #2046
Edit simply said, "That action is not available."
So I could not really test Save.
Hope this helps!
Thanks!
Daniel
