I've recently upgraded my system and accidentally set the wrong preference. I downloaded Photoshop onto my new set up and when prompted selected the wrong choice!
When dragging a layer mask into the bin it clips the image instead of just deleting the mask. The workaround is to right click the mask and select delete mask but after many years I am so used to dragging the mask to the bin.
How do I change this preference? Or is it a case of completely deleting and redownloading??
