CKEditor on Mac and Firefox. Problem: keyboard doesn't work after a selection.

Hi, I have this problem until we updated to Mac 10.8.2 Mountain Lion and Firefox 19.

When using CKEditor 4.0.2, if the user makes a selection and click in a place inside the editor, the caret is sown but the keyboard stops to work. i have tested also delete and arrow keys and they don't work.

I am adding the CKEditor to a div using an appendTo call.

The only attributes i am changing are: height, width and baseFloatZIndex

When i go to the smiley dialog the keyboard works again.

I had not been able to reproduce this error on Chrome, I guess it is something related to Firefox.

Thanks in advance.

Paco.
