Same issue, even last dev version of wysiwyg didn't work. So it can be marinelli issue.
It sounds like you need to change the css setting for each WYSIWYG filter to "editor default css."
- CKEditor 188.8.131.5275
- Wysiwyg 7.x-2.2+5-dev
- Marinelli 7.x-3.0-beta11
- I installed CKEditor 3.6.5 - did'nt work
- I another wysiwyg editor - nicedit - did'nt work
- I switched off wysiwyg module and installed bueditor and everything works with this light weight module.
