Subject Re: Problem With QueryServer In SQL Line Thin Client.

I can't seem to track down that error message to any specific line of code.

Do you have a stacktrace in the PQS log? I'm not sure the the message is 
implying that "localhost" is being interpreted as a class name or if 
it's saying the PQS at localhost had an error. The more details you can 
provide, the better.
