Problem solved. I needed to set includeVersions="false" to insure that the
formatter was not including assembly versioning information which was
obviously being changed everytime the asp app was recompiled. That would
also explain the problem in "finding" the assembly error message. Thanks to
everyone for the helpful suggestions.
