finding 10 words

two times I have found all 10 words and nothing happens. I am just clicking on all the letters for each word. It seems like the letters should disappear as you find them or something. I went all the way through with this twice and then it just sat there?

You have to hold the left mouse button down from first letter to last, like highlighting,, then release and it accepts word. Some may have S plural, some don't.

thank you so much. I thought I was going crazy!
