Those are all good points and should be addressed Graeme. Bleed air for several things passes through the AC system...so I have to dig a bit deeper into that switchgear and I suspect this will get addressed when I did into that. I plan to incrementely improve the systems once the IXEG/MU2 are ported to V12 in their current forms. As usual, I've added this to my tracking list.
Though it seems quiet here, I'm rolling full steam on XP still...the Moo just has to wait for its rotation across my desktop
