I use BL surrounding a BC because I think I have understood that it
"encourages" the BC to spread. And other BLs are surrounding.
It is a trial/error method but now I am stuck.
I wanted to show you a possible issue: indeed the layout is inverted, what
is CENTER is at the top and what is NORTH is at the bottom. This could be
of interest in general if a bug is discovered.
Back to my layout, text is not important, the BC do not spread, this is the
problem. If you will test the code, you can also remove something
redundant, or tweak it, so I have the solution, otherwise it is a bug, this
is of interest for you anyway, I think, solving this would shed light on
the subject..
Thanks in advance
