I can sympathize  :-)  It took me a week to get a tracking system with a 
Z-down/X forward coordinate system to play well with my Z-up/Y-forward apps.

Getting different coordinate systems to play well together is probably 
one of the hardest things to get right.  Fortunately, you just have to 
get it right once, then you can put the code inside a black box and 
never look at it again  :-)
