Re: using \break doesn't work or at least not as I expect

[Jay Hamilton, Sound and Silence]

Mats-
Thank you.  The problem then,  in this case, was that I never got a beam 
or any other mistake message/warning.  In fact, when I couldn't solve 
the problem I gave up with the different time signatures  in the problem 
(meaning hard to read) area and switched them both to 5/4.  I still 
never got printing warnings.
And I did do barline checks but as you discovered there is no 
information that is useful that can be gleaned from them in this kind of 
score.
I just changed the bracket to the correct one *and* changed most of the 
time signatures back *and* put breaks where they needed to be (using the 
pdf output- which I believe is the only way to check for barline 
connections in this kind of score).  With your help it's beautiful, 
playable, readable and closer to what I intended.

So is this a bug?  Since I never received any printout/beam warnings of 
any kind?
Jay
