To work around this problem on a Windows Server 2003-based computer, implement an exception handler such as a try-catch
block when you access the window.closed
property. If an exception is thrown, the window has been closed, and Internet Explorer handles the exception.
For example, use code that resembles the following code example.
window.onerror = showError;
var errorString = "eClient caught the following error on line "+ line +
":\n\n\t" + msg + "\n\nURL:\t" + url + "\nBrowser:\t"
+ navigator.appName + " " + navigator.appName
+ " " + navigator.appVersion;
var nw = null;
nw = window.open("about:blank", "blank",
var winIsOpen = true;
if(nw != null && !nw.closed)
winIsOpen = true;
winIsOpen = false;
<body onload = "openWindow();">
<a href="about:blank" onClick="closeWindow();closeWindow_again()">
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Server 2003 Service Pack 2.
