Why am I having problems opening windows programmatically?
<p>I have an application where I want a button to open three different calendars in separate windows.  The button has an action which references he following JS function: </p>

<pre><code> function all_calendars() {
    var target = "www.calendar_a.com";
    var title = "Calendar A";
    window.open(target, title, '_new');

    var target = "www.calendar_b.com";
    var title = "Calendar B";
    window.open(target, title, '_new');

    var target = "www.calendar_c.com";
    var title = "Calendar C";
    window.open(target, title, '_new');

}
</code></pre>

<p>Only the third calendar opens and in a new tab.  I would prefer three windows, though I gather that is a browser setting, but why does only one of them open?</p>
