I have a situation here, when I am closing the IE9 browser window before it finishes loading, then the browser is getting closed and reopen. This results in my web application to crash.
After some research in websites I came to know that this behaviour is due to the 'Hang Resistance' feature introduced in IE9. As a work around if I display an info message or the like to the user when he clicks on the window close button, then the crashing can be avoided. In my html file I use the below code to do this.
The 'doneLoading ' is a variable to indicate if the window completed the loading of contents.
In my application I am using this logic in a master page which has the <frameset> tags and <frames> inside it. The 'doneloading' variable is set to true on 'onload' event of frameset.
Now my problem is, the above Java script code is not getting executed always and I am not getting the IE warning message if browser crash always.
Please provide some input on why this message is not shown always.
