Well, I can't say I've had either of my cats step on the keyboard yet...but they sure do try and play along with me somtimes.(especially the one in my avatar photo. He is very brilliant for a kitty) So the back arrow is the better way to retry? I'll give that a shot next time. My solving percentage isn't that great this month so far, so I have to watch it. I'm short on patience with the really tough ones. Thanks for the hint!
