Thank you Serge. I just tried your suggested settings. But, while I can set the colour mode to Portrait, there' s no way I can use that slider...no movement possible at all. Same with every colour mode (slider not functioning).
Maybe I should do a new install of SPP (but I recently did, now on version 6.8.3...Mac)
