Hello All, I've got a weird symptom that I really need some advice on... I'm developing a live video socket-based application. I've got an impressive framerate with a 1 megapixel color image. But, I see a 2 second lag in my video feed across a 100MPS LAN connection. I've traced this lag to "whatever happens after TCustomWinSocket::SendBuf()". I tried to call Application->ProcessMessages() to force windows to process the sending event immediately, but it had no effect. My assumption is that the SendBuf command posts the event message to Windows and Windows doesn't get around to actually sending bytes across the LAN cable for 2 seconds. Is there a way to kick Windows in the pants to process my event immediately? Or is this a typical Windows overhead issue? I'm hoping for the former... :( Thanks so much! Rob
