Many thanks Borislav, works a dream !

>>I am working on an application that uses a top level form a the main form. I thought I could issue an on shutdown to control how the application closes. However the command doesnt seem to work. Is there anyway I control how the application closes when a user clicks on the close box in a top level form.

>>Many thanks in advance for any help on this topic
