TinyMCE error on IE 9

Yii 1.1 Extensions
1

I’m getting 2 errors when running TinyMCE on Internet Explorer 9.

  1. SCRIPT438: Object doesn’t support property or method ‘recalc’

  2. SCRIPT438: Object doesn’t support property or method ‘parentElement’

The 1st one occurs are the page loads.

The 2nd one occurs when you click inside the TinyMCE area to edit.

Also, I am unable to save any changes.

Appreciate any help.

Thanks.
