Gregorio,

Thanks for your help:

I am using my own form as a "menu screen".

Presently:
(1)My first form (main menu screen; mainmenu.scx) is set as "2-As top level form"
(2)My second form (example; saleorder.scx) is set as "2-As top level form"
(3)My third form (example; saleorder_items.scx is set as "1-In top level form" and the WindowType is "Modal"

Are the settings correct as per your understanding of my requirements?
If I change my second form to "1-In top level form" my toolbar associated with my second form freezes.

Also, upon "DO"ing a form (example: saleorder.scx) from the mainmenu I wish that form (saleorder.scx) not be able to load again, until the first instance of that form unloads....? Is there any sopecial trick to this?

Thanks again,
