There is also a bug in the WebHome page where there should be an Up Arrow gif that is not dislaying and the underlying header is munged.
It would be cool if you could report the bugs you encounter along with a detailed description on the project's JIRA over here : http://jira.xwiki.org/jira/browse/XWS . This will make it easier for the dev team to sort them and to have them eventually corrected.
