Colour Overlay, selectable area issues
I've been using PS for years and I'm pretty sure this is a setting issue somewhere but I am totally baffled.
Usually when I am working with png image of a unique shape I can go to : Select>all then grab the move tool and gently click over the layer and it will select the outline but for some reason it's not working on my layers. Similar issue when I try to use paint fill or brush etc on the layer, nothing happens. So for example my layer image is currently grey, I want to make it white so would simply click the paint fill over it but nothing happens, I can't even manually brush over it or use the image>adjustments>hue.
I've checked the basic things like modes to make sure it's all normal, I've tried RGB and CMYK but still no luck.
