Commented Unassigned: Gridview buttons don't fire with htmleditorextender on the same page (IE 11) [27621]

I created a simple page with a gridview that has a button field. I also added a textbox/hemleditorextender. Buttons do not fire postback in IE 11. Seems ok in previous version of IE.
Comments: Thanks, but i'm already using Server 2008 and .Net 4.5.
