Any help greatly appreciated.

Check if this is happening with the latest version from here http://www.igniterealtime.org/community/docs/DOC-1822

unfortunately, until it comes out of beta we won’t be able to deploy in our environment.

Well, i ment only to test with that version to see if this is fixed in the current code. If this is only happening with the 2.5.8, then cant help you and cant file it as a bug.
