Heh. Forgot to state that it does cost an arm and a leg but it's one of
the few software packages that is worth considering paying money for IMO.

Are you using 2 separate apache processes or 2 virtual hosts within the
same apache process?
If it's the latter, according to Apache's documentation:
"If no matching virtual host is found, then the first listed virtual
host that matches the IP address will be used."

It seems that my mod-perl virtual hosts are mixing
