I don't believe that numeric precision is fully supported in 6.5.3 - I
think there is much better support in 7.0.2.  Type inter-conversion also
seems to be improved in 7.0.2, but I can't comment on the specific issue
you have here :-)

I actually hand-edit my database creation scripts rather than using a
direct DDL generated from Access.
