>What do you need to intercept the user for when s/he leaves a command group? In order to leave the group the user must leave a group member, can you just use the LostFocus() of the buttons.

thanks but no thanks! - I want one or two lines of code and I want it generic. If I do it that way it would require amendments to all the command buttons. I think Marc's suggestion is closer to my needs... modifying the classes but I'm an extreme novice at that so it should be fun! Watch this space...
