flash actionscript: Hello,

I am new on these forums, and pretty new with Flash but I made a couple of
simple websites. I am currently working on a Flash Desktop but I can't open
specific URLs with buttons. I can open programms, and all other files with an
extension. But since internet shortcuts don't have a real extension it doesnt
open them, and if I use this code:
on (release) {
getURL("http://www.websitename.com", " _blank", "POST");
}
I use the same code to open programs like internet explore, but I just can't
let it open a website this way. It doesn't even open a screen when I use the
http://... I also used JAVA Script but that didn't work either.
I hope that my english was good enough to make my problem clear, and please
help me out, I already wasted two weeks of my life googling for the answer...

Never mind, I finally solved the problem by just allowing it by changing
settings on some macromedia thing, don't know exactly what I did, but I just
made it work :D Thnx anyway if u were willing to help me.
