First time XWiki user. I had previously demo'ed Milestone 3 on a different computer and it worked fine. Milestone 4 I cannot save edits to a page from the WYSIWYG interface. I'm logged in as Admin and on the default first page and saves from the WIKI interface are working. I was using JRE 1.6 and have now backed down to JRE 1.5 without success. I have not opened a bug yet.
