Flash Buttons & HTML Frames issues

I’ve seen this issue around but have had absolutely zero luck with finding a definite solution…

I’m using both HTML frames and Flash movies on my website and have created a navigation bar in Flash. The nav bar sits in one frame, and I’ve linked the buttons so that that they should load all content into the other frame. The problem is, when I click the button the link opens up not in the specified frame, but in a new window. This is the AS i’m using for my navigation buttons:

on (release)
    getURL("example.html", "frame name");

I’ve tried just about everything I can think of and am at my wit’s end. Any help would be fantastic:sigh:
