OK. Understood. But i think something is quite strange (it's UI, only). Alpha Channel is displayed in the upper part of the window. I thought this part was made for permanent informations (such as primary channels), but it seems that the alpha is dealing only with the active layer. Does anybody have an explanation of that behavior !
