Hey guys, After posting this I realised there was a way to remove any Prototype reference, which made it clear that it's some issue with Firefox.
A test page with the simplified code is at http://advancedcontrols.com.au/parent.html . FF displays "false", while Google Chrome displays "true". Anyway, it's useful to have this issue archived here, particularly the fact that including Prototype in the child is a work-around. -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
