Hi John,
Is this reproducible in a small self-contained sample application? If it is, can you email your sample application so that we can test the issue on our end. With this sample application, we will be able to track the issue and possibly provide you with a possible solution. Can you send the sample application to support@xceed.com and make a reference to this forum post so that we know it is you?
