Simon,
Wow, those are some really long filenames. Ever thought of putting that info in a metadata field instead?
Regardless, you could be showing the {filename} variable in your Info Text and you would definitively see the name in the Info Text pane and there would be no doubt as to which file is which (only the selected info is shown, the other pane does not have its metadata displayed at the same time.)
HTH,
