Reproducible: Always Steps to Reproduce: 1. Crash Bon Echo as described in bug 337349 2. Restart Bon Echo 3. Restore the session 4. Open the second window Actual Results: The first window will take focus and cover up the taskbar completely. The second window will be unable to be maximized. TalkBack ID TB18495137M screenshot(s) of behavior in play are attached to this report.

The problem is the null parameter to openWindow in _openWindowWithState. See bug 277798 comment #6. Replacing the null with an empty nsISupportsString fixes the issue: var argString = Cc["@mozilla.org/supports-string;1"].createInstance(Ci.nsISupportsString); argString.data = ""; ....openWindow(..., argString);

here's a patch for the fix as simon described it. i can't reproduce the problem on a mac, so i'll get a windows build going and try there.

I'm having the exact same problem. However, the second window also causes Windows to refuse to show the taskbar unless you press CTRL+ESC or the winkey (I have my taskbar on auto-hide). As soon as I close the broken second window, the taskbar reappears correctly when I move my mouse to that side of the screen.
