Impossible to move the layer

[COUTIER Eric]

Hello everybody,

I've noted that the original layer is impossible to move. When you click on
the layer in the layers window, the "bottom" and "top" arrow are grayed
(even if you've created another layer in the image after). The only way i've
found to can move this layer is to duplicate it then delete it. The same
thing occur in Paint Shop Pro but when you rename the original layer (for
example from "background" to "toto layer"), then you can move this layer.
Perhaps it's a good idea, no ?
