John,

Bruce has given you a fine solution to your question. But you might consider another approach, which is to create a Top-Level Login form and run it with a READ EVENTS after DO FORM MyLogin or oLogin = Createobject(...) however you do it. Then CLEAR EVENTS in the Login form when the user closes it. Then based on the outcome of the user login, I either bail them out or do my application setup and make the desktop visible, which for me is _SCREEN. Just another possibility for you to consider.
