Hi, Have you tried to launch a new thread in an ASPX page? Actually, I've tried it, and it gave me unpredictable results. I was sending 20 different e-mails in a new thread launched from an ASPX page, and sometimes i got 14 identical letters, or 6 different ones, or whatever. Seems that all threads started in the scope of the ASPX page are killed when the page has been sent to the client. However, I don't know if that applies to a thread started in Application_Start.
