[AS3] TileList event click problem

[lukamilani]

Hi there, i develop in AS3 a Flash application and everything work fine.
Before release i tried to test it in some different operating system

In a Mac OSX 10.5.4 using Firefox 3 i have this problem with a TILELIST

Shortly the event is not fired when i click over the item in the Tilelist in a Mac

_listCam.addEventListener(ListEvent.ITEM_CLICK, changeHandler);

//_listCam.addEventListener(Event.CHANGE, changeHandler);

p.s. i tried both case, but never work

Anyone can give me a tip ? i already tried a lot

Thanks in advance, Luka
