WymEditor problem with IE 9

I added to my web WymEditor. Everything works fine on firefox and google chrome. The only problem is IE9, where when I opening page with wymeditor, the new empty tab opens also. This is some kind of problem with iframe, I was searching for it in wymeditor code and found this : " //This function is execut开发者_如何学Goed twice, though it is called once! //But MSIE needs that, otherwise designMode won't work. //Weird."

Does anyone know how to fix it?
