加载多个TinyMCE实例会冻结浏览器，解决方案?

I have a page with multiple tinymce instances running at the same time and it's freezing the browser whenever it loads. It's taking not less than 15 seconds of waiting before I could use the browser again. I've tested this on IE9, FF6, and Chrome and all of them are freezing for some time while it is loading.I have a page with multiple tinymce instances r
