eZ Publish Online Editor 5.0 is a replacement for Online Editor 4.x. It uses the tinyMCE editor, which means that it works on IE7 Vista, supports full-screen editing, provides resizable edit area, and a lot more, out of the box.

eZ Publish OE is very powerful and can be a valid substitute for the official WYSIWYG editor. It is included by default in the newer eZ Publish 4.1.x branch.
