Hey Dave.
Does it pass design checker?
Does it say it has published successfully?
I guess with an admin form you might not get the same validation but I am guessing it is something in what your adding. Have you tried making copies of the views that you know work. I have had issue with timeouts buts not that blocked the form.
I also have has issue wher the form works to submit but not with email.
If this is a mission critical issue you can purchase some support credits and you can get help from the guy who coded IPFS. http://www.qdabra.com/products_all.asp?cat=12
