excel 'begin a group' menu line color
 

I have changed the Windows background color to 121 121 81 so I can use a pale
color for text. I have used this for years. I have now upgraded to Office XP
and find that this color setup renders the 'begin a group' line in the custom
menus almost invisible (126 126 114). I have searched the registry for this
color in order to change it but can find no reference to it.

Any ideas?

Many thanks in advance
