Bread-Bakers v101.n004.6

I used a Zo upright for years (model discontinued but still going 
strong).  I acquired a horizontal loaf Zo a couple of years ago as my 
second machine.
Problem:  if I don't watch the horizontal loaf and "rearrange" the dough, I
wind up with a lop-sided loaf.  It seems stupid to have a programmable bread
machine that I have to watch...
Any suggestions?
