Interesting case.
Appears that two sessions are crossing each other's ways. I have tried multiple browsers with multiple sessions working against the same Feedback wizard, to test for this. WSProxy uses the jakarta HttpClient library, which saves and reuses the cookies, thus the session, if started by the remote application. Maybe you will need to dump all HTTP headers to be able to track down the problem. Once you identify it, please let me know what it is, so we can discuss a possible patch.
