Thanks Pedro for making me think again if my old one worked or not. It seems preview and image window have some issues updating, that made me think it worked when it did not.

Maybe instead of a script it could be an option for the add layer mask dialog. What do people think about this other solution? Personally I do not think changing the behaviour (without option) would be nice, cos it will disallow effects that are based in already transparent layers plus extra control via the mask (think fading text layer or animations).
