I am working on an image in gimp that has multiple layers.
I just added a new layer, and am now observing some odd behavior.
I have three layers, A , B , C. C is the newly created layer.
For some reason, on layers B and C, I can not manipulate the pixels with any of the tools. For example I can not fill, or paint with paintbrush, or erase with the eraser. There is not X cursor, or any kind of cursor indicating that I can not perform the operation.
On Layer A, I can manipulate pixels, but only the non-transparent pixels.
I am not sure what more pertinent info I can give about the current image/configuration.
What could be causing the described scenario?
