OK, Noel, thanks for the information.
I have, of course read the mail from PG, stating they would solve the problem.
I have installed patch 509 as soon as it came out, and, of course, I am impatient!!
(have to relax and cool down, certainly!).
This does not answer the question: How do I link a given style with a demo in BiaB 2018? Let say I create a new demo and want to link it with a particular style..
The possibility of this manipulation existed under former versions of BiaB.
Anybody would know?
Bernard
