Mailto issue going nuts here

Never had this problem before so not sure why it’s happening now am I missing something?

I have a main movie that loads in other movies etc via xml , one of the external movies I load in has and email_btn that uses

 
Email_btn. onRelease = function(){
getURL("mailto:myname@mydomain.co.uk") ;
}

when I test that MC on it’s own it opens up outlook, my problem is that when I test the main_mc that loads in the mc that contains the email button it doesnt work also doesnt work when i test it in a browser, not even a hand cursor
This is driving me nuts, any ideas.

In fact i have just noticed that none of the buttons in the swf loaded in via xml into the main movie are working, anyone have an idea why they are not working?? is there some kind of security issue im missing

my bad, i forgot i had a transparent button that lays over the container that loads the external swf.
