One method would be to use New_Form to start each form, and when you want to go back to the menu, use New_Form again to start the menu form. Each form would then run alone, and there would be no "stack" of forms built up. If you need to communicate between the forms, use global variables.
The above method may be frowned upon to navigate between forms, because it doesn't follow a "drill-down" pattern, but I know it will work.
As an alternative method, you might use exit_form from the called form rather than call_form('main'). Each of your subsequent call_form commands is what is building your stack of forms.
Hope this helps.
