dhtmlx.confirm and IE9

Hello, The following tiny snippet of code to produce a confirm message works fine in Firefox & Chrome but not Internet Explorer (IE9) , and I am at a loss as to the reason why, or how to fix it. Any suggestions? (the message.js/ message_skyblue.css are the latest from github). Thanks

[code]

<style type="text/css">
	body, html 
    {
		height:100%;
	}
</style>
[/code]

Want to know the answer?

At the very top of the code you need

to get Internet Explorer to work.
The end result isn’t perfect (ie it looks better in firefox & chrome), but is acceptable
