The query is already set to ReadOnly and I have fetched the only
record in the result set which means it should be at EOF. Although I
have fetched the first and only row, I have not tried to fetch until
EOF is True. Closing the query made the problem go away.

I am trying to port my application from BDE to IBO and it would have
been much simpler if I didn't have to worry about closing the queries
when I am done with them. That was never really a concern with BDE
so I was a bit sloppy about it. It's going to take some doing to
find all instances of this in a 200,000 line application.
