When creating a post or replying and clicking on the message textarea in Internet Explorer 11 the following JavaScript error is occurring in both 3.0.12 and 3.1:

Line: 352

Error: Unable to get property 'createRange' of undefined or null reference

According to the debugger the error is happening in editor.js in the textEl.caretPos part of this:

function storeCaret(textEl)

{

	if (textEl.createTextRange)

	{

		textEl.caretPos = document.selection.createRange().duplicate();

	}

}

Code is pretty much the same for both 3.0.12 and 3.1.
