In order to assist you best we need more addition information.
1. Reproduce the problem and send the trace log.
2. Please record a Jing video demonstrating the entire process, so we can better understand what is happening.
3. Please provide us with a copy of your test and if it is possible grant us access to your application so we can reproduce the issue on our end and give you a solution. If it is not possible to grant us access to your application, please take a Fiddler trace and attach it to a support ticket in a zip file. You can capture a Fiddler trace using FiddlerCap.
