Thanks for quick response - Understand what you mean about naming of files and possibility of not realising you've previously d/l certain files.

Am absolutely sure I haven't d/l some of these files before - the files that are showing these false "file completed" always seem to be .wma format - which I've noticed also seems to be same extension used by the notorious 119.kb & the other known dodgy file sizes.

Another common feature of these "files" also seems to be no entry in the "Bitrate" column - it's just blank.

Really interested to know if other users are noticing this or not - have only ever d/l audio files so far, so don't know if other types are effected or not.
