Just letting you know that I have run into problems with the nbsp too. Although I can't remember the details now and can't test it for you. I've now purchased the Online Editor because I'm tired of the bugs and am ready to move into production.
We are actually thinking about buying the Online Editor but the version we need cost around 2100$ (updating server version). That's why we're trying all the possibilities for the moment.
Thanks ( and always need a solution :( ) Benjamin.
