I don't, but your post answers a question of mine about behavior which
has always seemed a puzzle. Often I will wrap a complicated
computation in a Check in order to Abort[] on any message. Then, I
will sometimes get an Abort[], but no message! And, indeed, often
an NIntegrate is involved. When that occurs, I have never been able to
re-write the code to retrieve those missing messages.
So if there is a way to "unsuppress", that will be helpful to me, too.
