Ive notice occasionally Mezzmo picks up a file as its being copied into a folder. When this happens it deems the file invalid.
(Says "Invalid file found please check the log for details - on a side note, it be nice if I could double click this and be taken to the log !)

Once its gotten into this state I cant convince it otherwise - because it thinks it invalid I can get props or anything.
If I right click and say "PLAY" it opens VLC and it plays fine.
If I rename the file (or its folder) Mezzmo sees this as a different file and all is well. However, if I rename the folder back it flags as invalid again (presumably mezzmo is doing some caching ?)
I've tried doing a maintain folder but to no avail.
