When inserting a slide in version FM5.x at the end of the storyboard, all already existing images are shifted one position to the left to show the space for another image to be inserted.
In FM6, on the other hand, only a very narrow area for inserting an image is displayed at the end of the last image in the storyboard.
This leads to the fact that an image or a snippet is moved from the library to the desktop and deleted at the original location if it is positioned inaccurately, i.e. misplaced outside of the storyboard. The snippet is then no longer available, an image can be moved back.
