@xmanhattan:I have a similar problem in back-end with the new version of EventCalendar I'm currenty developing: if I place two TinyMCE editors in the same Tab, then the second one behaves the same way you described. It seems that TinyMCE is "sensitive" to other javascripts, like the tabulator script. I have yet found a workaround... Do you have any other javascripts enabled?@Tank:Most of the styles that you define inside the TinyMCE editor do not apply to the final result when the item is displayed. That is because the style is manipulated mainly by your template CSS files. So if you want to change e.g. the style of a span tag, you have to add/change the corresponding class in your template CSS file (customize.css).
