I added dried blueberries (Melissa brand) at the appropriate time for my
machine.  To make a long story short, most of the blueberries did not get
incorporated  into the dough.  The finished product had  most of the
blueberries concentrated on the bottom of the loaf.  What did I do wrong,
or not do right, to end up with the dried fruit at the bollom of the pan
and not mixed through out the dough? 

Thanks,
