I have a form with multiple subforms, and on each subform there are command buttons that I enable/disable from the parent form. When I have clicked one of the subform controls, I have the focus shifted back to the parent form which works fine, but when I try to disable the subform controls from a control on the parent screen, I get an error saying it can't disable a control that has focus and it breaks on the subform control that was just used. How can I get this to work for a subform that has data, and for a subform that has no data?
