Hi All,

(Sorry for the flurry of emails, but I'm trying to get back to working
on a piece and this is somewhat in the way.)

Just wanted to add some more information regarding the bug.  If I
recompile csound and replace the libcsound and executables, the first
time I run the test.csd file everything is fine.  After that, it will
consistently give a pop.  I tried replacing musmon.c with the previous
version from CVS (the one just before the remote stuff was put in) and
recompiling and installing did not clear the bug on first run (not
sure what that implies if anything).

Thanks,
steven
