Problems with getURL action on Mac projector -need HELP!

When I use the getURL action it doesn’t work on a standalone projector on Mac, it works fine in Windows and in a browser, but I need it to work in a Mac projector. Does anybody no why this is and more importantly how to fix it?

My script looks like this:
[color=Red]on (release) {
getURL(“http://www.site.com”, “_blank”);
}[/color]
