>Either way you have your answer.
That would provide an answer for that particular project but not all of them.
I guess I could copy each one just before opening them, it wouldn't take that long, I was just hoping someone had summarized the issues somewhere. Even if I found such a thread, I wouldn't know if the problems had been fixed but at least I'd know what to expect and possibly which plugs are prone to misbehavior.
It's not a big deal but my tracks have become more complicated over the years and sometimes I'd like to take a plug or two out of the loop without taking them out of the project.
