Visural dropdown have some issues with IE9

[Tarun]

Hi,

Sir I am using visural wicket dropdown in my application in a
registration form. And i have set dirty attribute to true. so that it
promptms me a message when i navigae to other page.. but in IE9 just
on clicking any dropdown i am seeing same message (Leave page or
stay ) seems to be that it is navigating to other page but that is not
the case.. However it works perfectly fine with Mozilla and chrome..

So please tell me what i need to do in order to make it compatible
with IE 9 also..

Please reply me asap.. I am stuck with this problem so badly..
