Hi Léo
I had this too, it's because inside the iframe there is mootools 1.2
and I assuem you use mootools 1.3 outside the iframe. the problem is
(afaik) that ape passes an object (that is extended with moo1.2) to
outside the iframe where you use moo1.3
then there will be a conflict.
solution is quite easy: just update the moo version that ape uses to
moo1.3 with compat, or try my fork:
