Hi Berta,
the notes in the whiteboard stay there after the break, so you will have them available in the second part as well.
I don't think there is a way you can resize the window, because the OnVUE program - once launched - goes full screen, and it 'takes control' of your computer, so no other applications are allowed to be running during the exam. I cannot remember whether the whiteboard can be resized, but it will remain on top of the OnVUE program: it is not possible to have some kind of split view to keep the exam on one side and the whiteboard on the other side of the screen.
