hi dalekandjedi,

here you didn't specify that which type of build you're trying with, if it's webplayer build, hope this link will help you.

http://answers.unity3d.com/questions/50138/open-link-in-new-tab-from-webplayer-hosted-on-any.html

void OnGUI () 
{   
    if(GUILayout.Button("Google"))
    {
        Application.ExternalEval("window.open('http://www.google.com', '_blank');");
    }
}

Is there a way to replace the 'http://' content with a variable and still allow the ExternalEval to work properly???

eg.

public var linkURL = "http://www.google.com";

Application.ExternalEval("window.open( linkURL, '_blank');"); ... does not work

So far I've been slightly unsucessful in overcoming this. Anyone know how to solve this issue???
