I think that this is fixed in the beta version of Vienna 2.2.2. It can be downloaded from <http://sourceforge.net/project/showfiles.php?group_id=142635&package_id=157268&release_id=560496>. Please try that and update the bug report here. Thanks!
I'm closing this bug. I can't reproduce the problem in Vienna 2.2.2, so it seems to be fixed.
