issue with double click with LoadVars with outside url?

This seems like it should be fairly simple!

I'm trying to use an outside .txt file which contains a url link that the .swf reads to direct the browser to another web page. The following code works fine, but i have to double click on the .swf to get the link to work.-- (it happens in both safari and firefox).

If anyone has any insight as to the double clicking issue or knows of a better way to do this, please share!

Thanks for any insight!

code in txt file:
link=http://www.thelinkgoeshere.com



on .fla button:

on (release) {
newURL = new LoadVars();
newURL.onLoad = function(success) {
if (!success) {
trace("fail");
} else {
//do whatever you want to happen IF successful
trace(newURL.link);
//newURL = your textFile & link = variable in text file
webSite = newURL.link;
//set button code
button.onPress = function() {
getURL(webSite);
};
}
};
newURL.load("url.txt");
}
