I [theText replaceSel:aString] text into a Text that is in a ScrollView.
It is all pretty vanilla stuff.

But recently (as I've added some other features to the program) the
displayed text has started to get garbled when I scroll.  It is even
an intermittant problem---I scroll, and get garble (missing characters,
what looks like overprinting, unexpected wrap) but when I scroll it off
and then on again, I get no or different garble.

So far as I know, I am not doing anything "clever," so this behavior
surprises me.  Any hints, clues, or suggestions welcome.

Sounds like you trashed memory.  Have you tried using MallocDebugger?
