Jean-Marc,
I noticed that the Document Settings dialog is partially broken in macos
(build with Qt-5.11.2).
When making a change to the settings (with the default document class)
the buttons (OK, apply, reset) are not highlighted. They seem still
active though, so you can click on them.
When choosing another document class they become highlighted.
The problem is absent in commit azf... (8/7/2018) and present in commit
b21... (10/7/2018) and I suppose it's related to the changes in
QDialogButtonBox.
Regards,
P. De Visschere
