If I understand correctly, both buttons should become disabled when you open a form. I think the most simple way to do this is if you place that code in the forms directory. Since you have a public variable to reference the tbrDesktop object you can do it this way:
In the Form's INIT write

tbrDesktop.SetAll("Enabled",.F.)

In the form's DESTROY write

tbrDesktop.SetAll("Enabled",.T.)
