Jason,
Can you explain what this patch is attempting to fix? Given that we are
in beta with 7.2, I want to fully understand the problem here before
applying this patch. (Especially given that the diff is pretty large and
not a one or two line change).
Also what testing have you done on this? (When you ask us to 'check
that it works', it doesn't give me a high level of confidence that this
is well tested).
thanks,
--Barry
