When "View -> Warning" in the tool bar is selected and the check is removed, the window for a warning message display no longer opens.
Since the message is recorded, when this window is opened by "Help -> Information," for example, going back and looking at the message is possible. Even is the above check is removed, if this window remains open, its message is displayed.
The ON and OFF states of this check are not inherited in the next dviout after dviout ends.
