By default, the AVM calls Dispose( ) on dialogs that inherit from Progress.Windows.Form when they are closed. Use -nodialogdispose to prevent the AVM from doing this. You can also control this behavior on a case-by-case basis using the DialogDisposeonClose property of Progress.Windows.Form. See ABL Reference for more information.
