My approach is to relief the main thread from any heavy lifting; calling web servers, processing data and preparing data structures. Calls to web servers should also not be made directly from the main thread. All that helps a great deal to keep the app responsive. Correction: Is essential to keep the app responsive. You need to understand how to build mutex' though. Calling garbage collection (in the background thread) is in a way just another operation which occurs in background thread processing. I stopped worrying about that a long time back. JP
