I was testing version 1.5.0.38 and detected the following malfunction:
1. Photo opened
2. Background layer duplicated
3. On this layer: a) Selecting blue chanel and B) created a corresponding mask
4. Changed the mixed-mode of this layer to "Multiply"
5. New (empty) pixel layer created and moved below "duplicated backgroun´d layer" in order to do some fine-tune burning
When I now try to fill this empty layer with neutral gray or try to paint using the paint brush on it or try to erase something from the top layer etc. -> nothing happens.!
(I hope I used the correct English terms for I am using the German IU - see attached Screen shots).
