{{Quickfixn}} Field 35 not found when connecting using FIX.5.0SP2

[Grant Birchmeier]

Yeah, SetField is a basic function that's used a million times.

It would be more informative to trace at SendRaw and/or GenerateLogon.  You
can look at the generated Logon message to see if it looks funny with
regard to 35.   (Though I can't imagine why it would.)
