[xwiki-users] Annotations not working

I'm running XWiki Enterprise 3.3. Annotations simply do not work (via Ctrl-M). I've tried resaving the Annotations pages (as per http://extensions.xwiki.org/xwiki/bin/view/Extension/Annotations+Application) using an id with programming rights. I've also installed the Admin Tool and used it to check programming rights (Admin.CheckProgrammingRights). Viewing page sources, it appears that annotation styles, code, etc are being included in pages. I've also turned the feature on in preferences. Am I missing something I need to install? Is there logging, etc, somewhere that I can examine? Would it be helpful to (re)install the Annotations Application (http://extensions.xwiki.org/xwiki/bin/view/Extension/Annotations+Applicatio… Or, since Annotations is bundled with Enterprise, is this targeted at an older xwiki version, so it would be harmful to do so?
