XnView for Windows 1.96 on Windows XP SP3 does not support to change an EXIF property if multiple images are selected. The expected/desired behavior would be to show the value of a property if it is equal in all selected files, otherwise to show either no value at all or the value of the focused file with grey font color (ghosted).
This feature would be practical for example to correct the orientation of multiple images in one go.
