'onblur' problem

Show all headers | View raw

HI:

    I have a <select> tag on a page that is on focus as soon as the user 
opens the page with his browser, and also that has the following 'onblur' 
property:

    <select etc, etc.,   onblur="chkentrymethod();" >
    ...several options here ...
    </select>

Normal Operation:
     If the user fails to 'select' one of the several options in the 
<select> tag, and instead focuses on another field,  I immediately 'alert' 
the user and re-focus back on the <select> element. I do this until he 
'selects' one of the options. Works good !

Problem Operation (at least for IE8) :
    If the user clicks the 'X' (eXit the browser) button in the top-right 
corner *before* selecting an option, my IE8 browser senses the 'onblur' 
event and shows the alert message -- even though by that time the browser 
has already shutdown.  Very messy of me to allow this.

Question:
    How can I sense that the user is simply closing down the browser, and 
stop the onblur event from presenting the alert() message.

Thank you.
