has its own editor just like that thread suggests. tinymce is another editor which is the issue here. It is an option we give users to try the tinymce editor for places we do not use the vb
editor but we do not support there code. There is nothing I can do to rewrite how there software works. If the advanced editor for tinymce does not work your option is to turn off the editor or set it to the basic one.
It is kind of like the flash uploader we include with the application. That is made by an external comany and included as is.
