[Quoted] I think I can. First, what you need to do in this common trigger is execute the builtin ENTER; as the first statement. This takes the place of the user hitting the ENTER key. The reason for the difference is that the WHEN-VALIDATE-ITEM trigger only fires when the "leave-the-item" event occurs. This occurs when you click on another field or use the keyboard enter or tab keys. When you use the mouse to select a menu item, the focus is still in the item whose value was entered. When you click on a button, the focus may optionally leave the button. The determination of whether the toolbar button gains focus or not is a property of the button. Typically you do not want to change focus to a toolbar button when it is pressed. I suggest you change the MOUSE_NAVIGABLE property of the buttons to FALSE. Then the toolbar button and the menu should operate the same way. But you will have to have the ENTER statement in EVERY TRIGGER associated with your toolbar buttons and menu selections.

Hope this proves to be helpful and accurate,
