These bad hyphenations are definitely a bug in your implementation, and
are not just a result of your using acronyms. I am
having the exact same problem, and someone else posted about this
problem a little while back, but I didn't see any reply.

Here are some hyphenations copied directly from a tex log:

      per-hap-s it-s s-lope

What I know is that this does not happen with the lplain format
that came with my implementation of Tex. It only happens with my
compilation of the AMS-LATEX format. I am using Radical Eye's CTeX,
NeXT version 3.1a, with AMS-LATEX 2.0.

Does anyone know why this happens? Is there something you have to do
when compiling formats to get the right hyphenation? Could people who
are having this problem share the details to see what the common
thread is?
