I'm afraid you would need to ask Fatwire developers about this as they are the ones who did the integration. Since this is the case, we do not know what they did, how they customized the editor etc, so unfortunately we are unable to provide any support here.
What is more important, FCKeditor was retired long ago and is no longer supported. It was replaced with CKEditor which is a far superior product, with lots of new features and bug fixes when compared to FCKeditor. It is most recommended to upgrade, so you should definitely urge Fatwire developers to provide an upgrade in their product.
