I guess your problem is that you get some junk in your screen after closing some forms, now when you close a form, let us say form_two you get some junk like "EM" on the screen at particular position of it, since "EM" is on that form and some how it likes to stick on screen. How to get rid of it ? Try this Open a form in a window "w_form_two", Now the problem would be when you do clear window "w_form_two" the contents will not be cleared, you can clear window other than the present window on the stack, so open a temp window 'w_temp" and clear window "w_form_two' then close window "w_form_two" and close window "w_temp" Result the junk on the screen would disapper. Good luck !
