Resolve issue where scalebar in the mapper differs from scalebar in the layout window in MapInfo Pro

Products affected: MapInfo Pro™
Note: This solution is only needed for 32-bit versions of MapInfo Pro.

 When the mapper and the map frame in the layout are different sizes, this issue can occur.

To resolve, make the mapper and layout map frame have the same height to width ratio:
  1. Add a scale bar to the mapper
  2. Create the layout
  3. Double-click on the map frame in the layout to get the height and width of the frame
  4. Use the Window Manager from the Tool Manager to set the height and width of the map window to have the same height to width ratio as the  map frame in the layout window.
  5. Add a scalebar to the layout
