2.49 vs 2.50, armatures and data blocs

Hi all,

I ’ trying to animate armatures in blender 2.5 and I have some problems.
In 2.49, actions are linked to armature data. But in 2.5, actions are applied
to the object, so differents armatures objets can’t share actions and have
different movements on the same time.

Is it a bug or a user pref option?

sorry, i posted on the wrong forum
(could the admin delete this thread ?)
