Using FCKeditor with ajax

Hello,

I have created a webpage that is split in 2.
On the left there's a tree with items. When I click on an item in the tree, then details about this item are loaded in the right right. In this details view, I have created an instance of the FCKeditor.

These details are loaded by using Ajax and work fine.
But when I click on another item in the tree, new details are loaded with Ajax in the right side of the screen. Then again the FCKeditor must be loaded but then it goes wrong.

I recieve a script error saying telling me that the programcode cannot be executed from a script that is released.

I don't know what it really means and how to solve this problem. I suspect that it happens because with Ajax I write the details with innerHTML in the same window. So when I click on another item it created another instance when to old one is not release/deleted?

I could use a simple textarea for messages, but I want to use the FCKeditor. Can anyone tell me how to make it possible to reload the fckeditor.

Best regards,

Mattijs
