I just downloaded Paint.net v3.31, and yes, I'm a newbie. Don't bite. I just need to find someplace that tells how to use it. I'm having problems with layering. How does one do that? I hit the "add a layer" button, and even though I've got three pictures pulled up, nothing seems to happen. For sure, they are not getting intermeshed. Is there a nice instruction booklet PDF for beginners somewhere? Thanks.
