Check if All Forms are closed

Hi there,



I am creating a few forms one of which is the MAIN FORM that closes upon opening another form.



What i am looking for is when another form closes, if no other forms are open, then open the MAIN FORM again.



Can I use this:

If CurrentProject.AllForms("BUT KEEP THIS EMPTY").IsLoaded Then ???



Thanks for your help in advance
