New window created when Microsoft Powerpoint is also running on a second display

[GavinSmith0123]

When I have a second screen plugged in (in my case, a "CleverTouch" interactive whiteboard), and run a Microsoft Powerpoint presentation, OpenBoard creates an extra unnecessary window on the same screen as the original window, which is very confusing. The only way to get rid of it is to close the program and open it again.

I managed to disable this behaviour by setting UseMultiscreenMode to false in OpenBoard.conf. I don't know what this "multiscreen mode" is for, but in my case it is only harmful. I could not find a setting in the GUI to disable it, requiring me to edit the settings file in a text editor.

Could I suggest either that "multiscreen mode" is removed, or that a GUI setting is provided to turn it off? Thank you for your attention.

In Multi-screen mode OpenBoard uses a secondary (and possible third, etc) screen to display a "student's view" of the board without toolbars. You can enable/disable this mode using the setting you found. This setting is also available from the OpenBoard main menu:

When no second monitor is connected, as it is the case for the screenshot above, the option is greyed out. But as soon as you have a second monitor you can enable and disable this mode here.

OpenBoard uses the main screen as teacher's view and the second screen as student's view.

Multiscreen is an essential feature of OpenBoard, so it will not be removed. You second proposal, the GUI setting, is already available ;)

I see, I hadn't seen that command or realised what it meant.

In my experience the two OpenBoard windows were on the same display and overlapping slightly when viewing a PowerPoint presentation. I suspect that PowerPoint makes it appear as if there is an extra display when it is in "Presenter View".

I will have to check how easily I choose that option when I have access to another display to test it again.
