Amazingly so, but tonight my Irfanview is repeatedly stopping, and there is nothing I can do with it, can't save it, can't do anything but start over! In this way it's more frustrating that when I started!!!
I think I may have put a band aid on it though, just saving it every time I change colors. That way it's at least part way done. I don't have to start at the beginning over and over. Whew...
