This is strange. A StoredClass does not have a matching a ReflectClass.

Waiting for database file from reporter. 

Neeraj Joshi - 04/Jul/07 06:16 AM 
Please upload the required database. 

Patrick Clemins - 09/Jul/07 04:03 PM 
The database is 24MB, beyond the maximum attachment size... Please advise
how you want me to handle this. I've uploaded it a couple times already to
a website per Travis' request.
