I will try what you are suggesting. But the problem is where to call my main application form from. From ukabrasives_app.prg for example?
Also I am trying to set in app_application cStartupFormclass and cStartupFormclassLib in app_application. I thought that's the best way. I have a message error which I have no idea about. Finally I get my form on screen but the toolbar is desabled and menu has all choices dimmed.
Thanks Mark
