Hello test cdb,
In order to help with your issue, we need more information about your test scenario. Please provide us with a copy of your test. Also, please provide your failure log and a copy of the DOM at the time of failure. You can export these to file from the failure tab for your test and add them to a .zip archive. 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. If you are unfamiliar with how to do that please refer to this short video. You can download the Fiddler application from here. A Jing video demonstrating the issue may also help us to better understand what is happening. Thanks for providing the information we need to advise you best.
