When I try to align various layers in GIMP 2.8, sometimes the align tool selects the entire image, not the layer I clicked on.
It doesn't matter how many times I try, and closing/reopening doesn't solve the problem. I've not yet discovered any regularities, it just seems to happen at random regardless of layer contents, size or position. It even happens with layers I'd previously aligned without issue.
Why does GIMP do this? Can it be fixed?
