We bought this machine a couple weeks ago at Bed, Bath and Beyond (wanted a bread machine quickly) and have used it at least 7 times. ALL the loaves collapsed! I called the service line and the woman said, add more yeast (already tried that) and then she ended with, it's not the machine. I can definitely follow directions and I know it is not me. After trying the recipe in the book twice, I've altered the flour, the baking time, the salt, the water, the yeast, etc. and still every time it is a sorry looking collapsed bread that tastes very good. It is such a disappointment.Update: After much experimentation found that reducing the yeast to 3/4 teaspoon prevented the bread from collapsing.
