Okay I've done some more poking around, and the attached patch to 
the OpenDBX MSSQL backend (1.4.4 tarball) fixes this for me.  It's just 
a one liner that adds setting tc->errtype to -1 in mssql_odbx_bind to
what it does when it can't connect.

Now whether this is a sane or sensible fix for this, and the
real problem is SqueakDBX, or something higher up in OpenDBX 
not being able to handle thing without this set and it's that that 
needs fixing instead, I really couldn't tell you :)
