Bread-Bakers v100.n046.6

Why is my wheat bread always heavy and a little touch?  Even adding gluten,
its is heavy and tough.  Also, what causes yeast bread to rise and then fall
when touched on the second rising.  Most often I use machine to mix and knead
(dough setting) .Then I make loaves usually small round loaves, and let them
rise about an hour at room temp.  Sometimes they rise and fall or rise too
much and if I touch them they collapse.  Can you teach an old dog new tricks?
