Jim,you may well be correct, but since I have just spent three days chasing my tail over this and found a quick fix, I am not prepared to spend more time on it.
Thank for your suggestion but I'll wait and see if Support come up with anything.
(From past experience these issues are quietly fixed in a future build without any acknowledgement of the original problem)

I have been using BIAB since 1997 think that PGMusic products are very good, but I find this annual round of glitches and bugs following the annual upgrade very tiresome and frustrating. My perception is that this became noticeable after the introduction of RTs and has increased over the years since then.

Before the self appointed BIAB apologists chime with the usual platitudes about complicated, sophisticated programmes, hard working developers and beta testers etc.
I use several complicated, sophisticated programmes for music and photography which basically work 'straight from the box' without having to be run as administrator and without the round of 'fix-it' after an upgrade.

Rant over,
