The question was fairly descriptive but I\'ll describe it further.

Basically, I have window1. Clicking a button link opens window2. Clickin

Update: This hasn't worked since Chrome (21+). The workaround is to close/reopen.

The following code works for me on Firefox (Mac & Windows), Safari (Mac & Windows), and IE8 (Windows, of course). I haven't tested IE6 or IE7.

However, it does not work on Chrome for either Mac or Windows. Specifically, clicking the button once creates the pop-up and brings it to the front. However, returning to the original window and clicking the button again does not refocus the popup.
```
<head>
  <script type="text/javascript">
    var popupWindow = null;
    var doPopup = function () {
      if (popupWindow && !popupWindow.closed) {
        popupWindow.focus();
      } else {
        popupWindow = window.open("http://google.com", "_blank",
          "width=200,height=200");
      }
    };
  </script>
</head>

<body>
  <button onclick="doPopup(); return false">
    create a pop-up
  </button>
</body>
```

does work. If it doesn't for you, we'll need a test case.

Some things that might cause problems: calling it in an event handler that fires before the button's window gets focus due to the click (but I don't think that'd usually be the case); running it on a browser that stuffs pop-ups into browser tabs instead.

(I agree with Max's comment. Pop-ups with cross-window scripting are generally best avoided.)
