Yes I was using a local connection, and using the
"localhost:d:\mydb.fdb" format seems to have fixed the problem.

Looking through the documentation, however, I could find no
prohibition against using a local connection in this manner. Am I
missing some documentation?

Also, what performance differences are there between the two
connection methods?
