Hi to All,

I used the Tools Customize command to create some custom button
buttons which I placed on an existing toolbar and assigned macros
to. After closing Excel and reopening the buttons vanish every
time. Why are they volatile and how can I make them permanent?

Thanks for your help,

Cheers,
