We implemented updatable cursors, but I think your driver have also to
handle sql syntax differencies.

It's fantastic

Well... if changing from 0.64 to 0.82 cause some problems it would be
fine to understand why it fails and wrote a small test. I usually use
ODBC trace or TDSDUMP to do this job (some test came from some Windows
program I wrote some time ago).
