I am using Movie Edit Pro 17 Plus.  I have Windows 7.   I am creating projects made up of both videos and stills using 16x9 images. I often in the past have used stills that were panoramas (having much greater widths than the normal 16x9 parts of the video.  When these panoramas were first inserted into the video in the edit mode, a black space would appear above and below the panorama after I dropped it into the video.  Then when I left clicked on the panorama selected Movement and then "left to right" the panorama would expand to the full height of the rest of the video with no black spaces above or below, and then pan from left to right.  I must have inadvertently changed some program setting because now for some reason the panorama shots will move left to right but there is still a black space above and below the photo.  In some cases the leading and following edges of the panorama shot also traverse the screen from left to right.  How do I correct this so the entire video has the same height and the black borders do not appear?
