Problem with SCAYT

First of all, sorry for the English.

The situation is this, if someone has experienced a similar problem.

Use the SCAYT, on a given page, I access many times without reloading the page CKEditor, CKEditor is loaded via ajax.

The first time the ckeditor is loaded SCAYT presents no problem, the starting time of the second, it returns the following error when I type anything.

TypeError: doc is null
doc.createElement tag = (tag);

Error disappears when I reload the page.
