Target Blank in Flash

Hi gang!
Have you ever gotten a security warning when embedding a target blank link in a flash file?
Here’s the code I have on a button:

on (release) {
getURL(“http://www.i-achieve.ca”, “_blank”);
}

Here’s the error I get when I click on the published file
Macromedia Flash Player Security
The following file is trying to communicate with this internet-enabled location:
www.url.com
To let this application communicate with the internet, click Settings. You must restart the application after changing your settings.
