dear firstdefence. I was able to rasterize the image and several tools and filters worked, BUT, after trying five things, the screen froze. Nothing was responsive----nothing! I could not close out the image or Affinity. I had to manually push a button on my computer to turn it off. When I tried to turn the computer back on, all I got was the same Affinity page with my image (which should not have happened). Again, all was non-responsive. I turned the computer off again and although the computer was turned off, it turned itself on and off until I unplugged it from the power source. I was able to get the computer turned back on again and immediately went to my installed apps and UNINSTALLED Affinity. This thing was acting like maleware.
