Thank you *very much* for that quick and right answer.
Now, I'm relieved as I finally can jump to Emacs 22+, in Ubuntu
and in Windows as well (sorry, forced to use it at work, while
still refusing to use Outlook!).
Weirdly enough, under Emacs22/Ubuntu, my groups are dark green,
and under Emacs23/Windows, with the same config files, they are
purple, as you saw them. Not important, though, as I have
color-highlighting working, and so I know where are the empty
groups and the other ones.
I'm sorry to have disturbed you with a problem that appears to
be within my .emacs file, but see the weird thing: everything
worked perfectly in Emacs 21 (Ubuntu + Window$), and never in
Emacs 22+ (on both platforms)... That's the kind of interaction
that's difficult to spot.

Thanks for the hint on how to do it properly...
Case is closed.
Please receive a grateful hello from Brussels!
Thank you very much,
Seb
