Noel,

Thanks for that, it sounds entirely logical and well worth exploring the results alongside what Kent too might advise.

If circumventing sforzando/aria restores BIAB usability without also removing from its arsenal something that some other function requires, I'd certainly consider the option if repairing/restoring usability to the present installation appeared unlikely. The fallback of course is simply a fresh clean install.

It is now already Thursday AM here (UK) however, and I really have to pull away now and get to bed but I'll get on to that in the morning when I will probably be more alert too!

I know you have put in some time on this for me, I want to be sure you know I do appreciate that!
