Mark,

Yeah, that is what we are doing now... we are setting it up. We ran the
setup of direct SQL/ODBC logging for about a week... it is way too unstable.
We have no choice now but to do it that way. I don't really know which
component to blame thought... IIS or PostODBC? :) Hehe, think I'll go for
IIS :) Because we are not having much troubles with PostODBC with other
applications.

Regards,

- Jonathan Marchand
