Mystery solved...
The array behind the table was a mutable copy from the prefs, but not a DEEP
mutable copy.
Strangely, I wasn't seeing any console messages about attempting to modify
an immutable object, until after I noticed that in my awakeFromNib method I
was programmatically setting up a column to use a checkbox for its data
cell. I commented out that code and set it up in IB instead. Then after
that change, suddenly the checkboxes would no longer toggle. I saw in the
console I was getting a message telling me I was trying to modify an
immutable object.
I fixed the code to use a deep mutable copy of the array from prefs, and
everything now works like it should. No more bizarre drawing.
