Paint and all similar merely post a window paint needed value - Windows won't send a refresh message until your process rests or finishes. The best way is to run your process in a thread that sends an update message to your main thread from time to time. Otherwise - Application.ProcessMessages lets your process handle any pending win messages. Its a real kludge - and I use it a lot :) Mick _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
