If you upload a file with a long filename the arrow_right.gif image is displayed on the link name instead of being placed on the right border.
The background-image is positioned with:
The link has a width of "padding-left: 12px" plus the length of the filename. If the filename is to long, that 95% will be too left and is displayed on the link.
The different "padding-right" by ":hover" will cause a visible effect, similar to the :hover-effect before.
