I'm pretty sure that I am dealing with 1.1.8 on both machines but I will
double check that.  For now I have just told people to continue with a
JDBC-ODBC bridge if they really need to run stuff on their NT workstations.
Otherwise since the unix box is the production machine I have just tabled
this for the next week or so.  If I do discover what the problem was I will
mail the list.
