Two thousand, two hundred and twenty three (2223). (How it got set
at such a specific number I do not know, since I would have chosen
some round number like 3000 myself.)

Yes, I kind of thought that meant a low value might be problematic,
but I have a lot of resources (am at a full gigabyte of ram now), so
I've always maintained large values for settings like these. (Again,
I don't remember setting that to the specific number of 2223, but
there it is.)

This would make sense, except for one glaring problem: scrolling down
the symbol list produces alternating results -- apparently completely
at random, not actually back and forth, but inconsistent. If this
were some cache loading up, then everything after a certain point
would display the same way. This is not the case. It alternates back
and forth as you run down the symbol list, with no apparent rhyme or
reason that I can see.
Best,
Yuki
