Bob,

>After posting this message, I decided to remove the BO project from the solution as well as remove the dll reference in the bin folder of Web project. I rebuilt to see if I would get errors based on the fact that BO was no longer referencable. I then re-added the BO project and dll reference and the problem went away.
