Hi Arno, > If that happens with a fast network connection (LAN) then it's a normal behavior in > main, GUI thread since paint messages have less priority than messages actually > posted to the message queue.
Yes, it's happens on fast 1 GB Lan and very light and fast smtp server on second PC. No firewall or antivirus installed. Program works fine until message size is small (2-3-5-10 kb) and start slowing down since 40-50 kb. And hangs on 1+ mb. Is there any way to increase paint messages priority ? Or process it manually ? Or maybe increase SmtpCli send buffer size to 16384 or 32768 ? >In such cases you should move the SMTP task into a worker thread Yes, current version of my main App uses SmtpCli in threads. But I want to move it outside threads and eliminate some problems with synchronization...
