Postback with HTML Editor extension on page causes JavaScript error in IE11

I added the HTML Editor to the page I'm working on, and now ANTITIME I am invoking a message on the page. I get the following Javascript error:

JavaScript runtime error: invalid argument.

And after that, nothing happens. This works well in IE10 or lower and in all other browsers that I know of, however it does not work in IE11, which I need. Does anyone know any fixes for this problem?

This seems to be a known issue with AjaxToolKit. Try pasting this below the header:

<meta http-equiv="X-UA-Compatible" content="IE=10,chrome=1" />
