Disable editing and command buttons

Appologies if this has been asked before, I've had a search through the help forums but I haven't been able to find antything suitable or anything that works..

Is it possible to disable the FCKEditor instance? Depending upon the state of our application a form may be read-only or editable so I'm looking for a method of enabling and disabling the control to bring it inline with our form.

Thanks for any help and advice.

Paul.
