Thank you for your post, and I apologize for the late reply.
Are you using FileMaker Pro 11.0v3? If not, please update and try again. If the problem still exists, then I would like oto get a clone of the file so I can work with the file here. A couple of other users have reported a similar issue, but our Testing department has had trouble reproducing the issue. Check your Inbox at the top of this page for instructions where to send the file.
