ck editor 4 - two problems

Hello -

I've installed ckeditor 4 on my site. Overall I like it, but am having two problems.

1. How do I set the tabindex. My users want to tab in and out of the editor and currently they are not able to do so.
2. The .destroy() method is Not working in IE9 - details follow:
   • After user's submit their content, it's important that the editor instane is destroyed.
   • When I use the .destroy() method it works in chrome and firefox but not IE 9
   • Following is my syntax - replyTxtarea is the id for my html <textarea> element.

CKEDITOR.instances.replyTxtarea.destroy();

Any assistance in this matter is appreciated.

Thanks in advance - Pavilion
