I am switching views within the window. The orientation is sometimes confused.
Within one of the windows, when I attempt to display a popover which should be attached to a toolbar button, it is displayed in the location on the screen. If I physically change the orientation of the device, the popover is redraw in the correct location. If I switch it back again, it is drawn in the correct location. If I dismiss the popover and try to display it again, it again displays in the wrong location.
Suggestions appreciated.
