Subjectcsound ppc extension conflict
I recently had problems with csound's pvanal function. Csound seemed unable
to resynthesize pv files without creating   a lot of distortion. I was also
experiencing other general perf problems. Running Conflict Catcher (praise
be - we are not worthy) isolated a rogue extension called
ppcexceptionenabler as the cause. I have been unable to trace the source of
this extension, has anyone else heard of it? And has anyone else got any
interesting csound/extension conflict stories?  I'd love to hear them. Yes,
I'm THAT boring.

Hmmm...

As far as I know, unless you are using Digidesign hardware for sound output,
Csound PPC uses no extensions (except maybe sound manager).  There should
certainly be no extension involved in "pvanal" and it is hard to imagine
how an extension conflict could cause distortion.

Probably the ppcexecptionenabler extension has something to do with mixed 
mode execution (running 68k apps on the PPC chip) and was surely put there
by Apple, although it isn't on my machine.
