I stumbled upon a problem with IE 9 when Sending an Email, or doing anything to paste from another document to Class Creator websites. This did not occur with IE8, nor does it occur with the new Firefox 4.

What happens when the system asks if you want to filter the pasted material, and you appropriately answer YES, the screen will pop up partially, but no ability to actual paste. LOCKED, can't get out through Cancel or normal things.

As a result, usually all your work up to that point is lost.

There are some issues with the editor and IE9. IE will likely update the browser, there's always little issues when a browser is new. One way to get around any IE9 issue you're having is to turn on Compatibility Mode. That'll get you past any issues that have been reported. We'll also be updating to a new visual editor shortly.
