You could use a modeless form. You can put anything you want on it. In your startup code you DO the form, do some processing and then release the form.

I use this code to display a splash screen.

*** Display Splash Screen
DO FORM "Splash.SCX"

Setup vars & menus, prompt for password, open databases, etc.

*** Close Splash Screen
RELEASE WINDOW "Splash"
