Hiho!
Until now I had thought, "groups" and "backgrounds" where simply
synonyms, but they are not. You can access non-placed-bgs only by
referring to them as bg, not as group. You can say "place bg x", but not
"place grp x".
That is Ok by me... I think they share a lot, but is there not another
difference: Groups don't have to recieve messages from objects they do
not contain, but as they are backgrounds they do. Is it reasonable to
add a property to them that governs this distinction?
Regards
R�diger
