I am sorry to hear that this issue still exists.
Unfortunately I am still not able to reproduce this behavior with our latest official release 2013.2.1327.
In order to help you best 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 direct access is not possible, capture a Fiddler trace and attach it to this support ticket in a zip file. If you are unfamiliar with how to do so, this link
will provide you with step-by-step instructions for download and use. If taking a Fiddler trace please be sure to:
1. Click Clear Cache first
2. Check Store binaries
3. Check Decrypt HTTPS traffic
Hope to hear from you soon.
