Thank you. I don't know whether I can get away with calling this a
'bug', but it's a pretty severe 'glitch'. (A 'bug' is a deviation of
the program from its specification. A 'glitch' is a deviation from what
the specifications ought to have been.)
It seems obvious that the 'current' dataset, the one that shows up as
primary in the menus, should be the active dataset. Could this be put
on the list, as a deficiency to be fixed?
I did write 'obvious' deliberately. "'Obvious' is almost synonymous
with 'inadequately examined.'" Perhaps there's a considered reason why
the 'current' dataset is not always the active dataset. But if so,
could the philosophy of how the 'current' dataset is determined, be
given in the documentation?
-With many thanks,
Richard
