The testing drivers 8.4.0101 psqlodbc30a worked fine. Wonderful.

Is this a rollback to the previous behavior, or does this version use 
different code for the client side cursor? Or, I suppose this is a 
better question: Is this a permanent fix that will be included in the 
next official release, or is it a temporary fix just for me?
