Flash Actionscript With XML has trouble loading onClick

If you go to that page and click the deck of cards. Some clicks don't work. Most clicks do. This onclick problem also happens when testing the movie in flash.

my xml is structured like this

You may have done this already, but to discern if its the actually event or your code which is creating this problem, stick a trace in the buttonClickHandler before you do your loop.

I'm interested in if the event is actually firing when you click that deck...
