Austin, thanks for filing the bug report and
thanks Sven for fixing it so quickly.
I was hoping you would file more general bug report to capture the idea
you mentioned of "Do what I mean" (I cannot think of any other way to
describe it, sorry) and see if there were other areas where similar
problems were occuring. There might be other areas were it would be
better to do something rather than do nothing.
There is a case that I think is similar: if you are moving a layer down
the stack and the background layer has no alpha channel you get the
Layer 'Background' has no Alpha. Layer was placed above it. [ OK ]
