Vi, Yes I was able to fix it. It turned out to be the ShowInTaskBar form property which I had set to False. Changed it to True and all is now as it should be. I used the False setting because I am minimizing the form down to the task tray rather than the task bar. Obviously the Windows O/S sees that and decides not to display the application icon during an ALT+TAB operation. I can live with that and work around it programatically. Thanks for your help. ...Steve
