Ensure that Windows is configured to show windows contents during resizing. Start apprunner. Once the smoketest page has loaded start to resize the frame horizontally so that the the frame and contents are redrawn each time. Keep reducing the size horizontally until the scrollbar appears and continue reducing the size. As the frame is redrawn each time during the live resize, the horizontal scrollbar jumps halfway up the page and then immediately moves back down again.
