>I don't know why but I cannot see the shortcuts underlined in the Main Menu items of my AP Transaction program. I am using Windows XP as my workstation. Why don't the underlines (shortcuts) display on the main menu items?

You need to turn them on (it's been this way since W2K).

Right click on your Windows desktop, and choose Properties. Then choose the Appearance tab, then press the Effects button. Uncheck the check box "Hide underlined letters for keyboard navigation until I press the Alt key".
