J> I have a client software. On some of the PC, when the client J> is connected to the server and wants to send some data, a twsocket J> OnSessionClosed() event is triggered with an error code of 10053. J> When this happens, it will happen again and again. Other applications J> like IE, firefox, email, etc. on the same PC seem to work fine. J> This problem didn't happen before even on this PC. And a similar J> problem happens on some other PC as well. Any idea what can cause J> this? -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
