ShortCutKey not working...

Hi! I built a form with a menu button, but the ShortCutKey i wanna use is not working…i copied the menu button to a new blanc form and there it is working…so it is only not working on my form…any idea to solve this? i copied the frame i use and the buttons to a new form, but it is also not working…so…i have no idea how to solve this now. cheers Stophi

Ok…i had the button on a tab…but is it not possible to use shortcutkeys on tabs? even if i have activated it? when the button is not on the tab it is working… cheers
