Usually it is, however there is a small difference between GUI messages being queued in the message queue and notification messages from winsock being sent to the hidden ICS window directly. If you transfer on very fast lines it may happen that there's no time left to retrieve and process messages from the message queue if those notifications from winsock come in fast enough. WM_PAINT and the like are queued and so have less piority. That's why the OP saw an improvement calling ProcessMessages from a timer event, timer messages are not queued as well. Be aware that calling ProcessMessages from any ICS event handler can lead to strange and buggy component behaviour. Never ever call the message pump from component's event handlers, except you know very well what you are doing. -- Arno Garrels > > On Sun, 11 Nov 2007 09:25:31 -0800, you wrote: > >> I have a simple program that downloads a large file using the HTTP >> Client.
