Yes, that works. Many thanks.

I couldn't comment on that.

If a window is opened in front of the backdrop, so that it partially
covers the iconbar, ToggleBD causes the backdrop to cover that part of
the window in the area of the backdrop. The part of the window in the
area of the iconbar remains visible, with the iconbar behind it. The
window stack then comprises backdrop, open window, iconbar.

Well, that explains the misunderstanding! With respect, that is not what
is suggested by the names of the options, nor their descriptions in the
StrongHelp Manual.

Since 'Lower ...' does exactly what is expected, when running on RO4.39,
5.19 and 6.20, I do not understand the purpose of 'Raise ...'. I would
suggest that it would simplify matters, and avoid at least one problem,
if 'Raise ...' were to be removed: the user would no longer need to make
an arcane choice, and ToggleBD would continue to perform, which it does
very well.
