Yes. !x.style =1 and !y.style =1 in the startup.

That is not the problem. There is a "hole" where a maximum should
be, not a minimum. The behaviour remains when I create levels both
above and below the range of the data.

One odd thing, using /fill the file size 0.4mb. I just created the file
using /cell and it is a whopping 78Mb (yes megabytes). Obviously
something crazy is going on, that cell is handling it (in a thrashing sort
of way)
and fill is dropping it.

I'll reduce the code and post it.
