Yum-a-licious Lime Squares

I got this recipe out of a cook book I borrowed from my MIL and have no idea which one any more. I had never heard of lime squares before, and felt adventerous. Boy was I pleasently suprised! These were wonderful! My husband wasn't sure about them because it had pecans in it, but he loved them too! Prep time is just a guess. I never timed myself and haven't made this since Christmas.
