Hi, I have a bug in Roassal2 when I expand the Roassal2 window to fullscreen or if I open with the different size than default, the size of the view is too small view := RTView new. view @ RTDraggableView. el := (RTBox new size: 50; color: Color red) element. view add: el. view openInWindowSized: 1200 @ 720 With this example you have to drag the view to see the element -- Cheers, Leo Perard University of Lille 1
