I am at a loss with this one!
My tools, whilst showing when applied are not carrying anything out. eg in-painting Pixel layer, brush showing during application in red, in-painting then commences AND - nothing happens!!! There must be a switch somewhere but I can't find it. For good measure I also tried rasterising the image. No, that didn't work!
Tried another tool - clone brush -indication that it is doing the job BUT - it doesn't!!
Help please! Mike
