Difficulties with addWindowClosingHandler in IE

I have installed a WindowClosingHandler to catch when people leave my application without saving any data they have entered.

In my application, some HTML text is stored in a database and displayed on a page.  This text contains an <a href="javascript:function()"> element.  When I click on this element, IE calls my window closing handler.

I have read through https://groups.google.com/forum/?fromgroups=#!topic/google-web-toolkit/vaxeiEvNoUs which references called ClickEvent#preventDefault in a click handler to avoid this problem, but this is not possible since my code is not actually responding to the click event; it's the browser doing it in response to clicking on the <a> element.  Having the content come from the database is a strict requirement; it can't become part of the application.

Is there any way to deal with this?  It doesn't happen in Firefox or Chrome, but most of my users will likely be using IE.

Thanks!
Ryan
