Hi Joanne, Yesterday I received this answer from my TSM about this issue: Background Info: Clearing the browser cache or doing a force-reload in the browser showed the new version. A 304 Not Modified header was falsely being sent by tomcat when requesting content from the CS. This was due to a temporary workaround for an IE problem with WebDAV, which has been resolved in AP3SP2 via a Xythos update, thus the workaround could now also be removed, making the new versions appear again. Resolution: This issue is resolved in Service Pack 2 for release 6.3, which will become generally available in a few weeks. Seems that the problem will be solved in a few weeks.

A particular issue for us, is the fact that documents stored in the CMS are not being refreshed when they are overwritten/updated. I remember seeing some dicussion about this a while ago, and was wondering whether anyone has found a workaround? Regards Jo VLE Manager The College of Law
