I'm glad you were able to get your problem solved. I have seen inconsistencies with how Server.Transfer vs. Response.Redirect work on different OSs. I'm not sure why though. I'm wondering if the Response.Redirect, since it needs two round trips, is causing some kind of conflict in your case with threading.
