Hmmm...guess it needed 3 pairs of eyes!!!

Problem is, on XP atleast, is seems that webapp gets installed as "kiosk"
not "Kiosk"  :-(

Howdy,
It's not being deployed twice: two apps are being deployed, Kiosk and
kiosk.  That subtle difference is your problem.  Make sure the context
XML file has the same name as the docBase, it's case-sensitive.
