Bread: crumbling

dallasm, Aug 3, 10:19pm
I have a problem with my bread. I am using a Breville breadmaker and Alyson Holsts bread making book.
(a) the bread rising so high it sticks to the top and then sinks back down
(b)After 3 days the bread goes all crumbling.. it wasn't before so I dont know what I have done.. it would make good breadcrumbs.

I am sure that I haven't changed anything
