I have been doing your puzzles for years. It is unquestionably the best
jigsaw program around. I use it perhaps more than others because I am a
senior citizen with a wife who has Alzheimer's Disease. Accordingly, I am
in the house most of the time, and considering the material on TV, I spent
much of my waking hours in front of the computer, and many of those
playing Brainsbreaker.
