javascript error: wikiEditor is undefined when saving

Hi Just installed the newest and greatest XWiki - 1.0-beta-5.2310 and finding that I get a javascript error when I try to save documents. Message: Error: 'wikiEditor' is undefined Happens only when I save from the Wiki editor. When saving from the Wysiwyg editor I do not get the error. Running on Window 2000, Tomcat 5.5, MySQL, IE 6.0 SP1. My content does save - just have to wait for IE to tell my that it has an issue. Such an obvious error - makes me thing I have a config issue. Any ideas what is wrong?
