The new version 1.0.0.3 seems to be a little faster, however, I have come across an anomaly that I can’t quite pin down the exact cause of.
When I add files, let it do it’s thinking, find the correct season and episodes, when I try to save the metadata, it will save the meta data and then fail at renaming stating that its in use/open. The only program it’s open with is Metadata Editor itself. This only seems to occur with the first couple, usually just the first 2, then it’s ok. When I go back to the ones it says are open, it then can save them fine, usually after I’ve done episodes 3 to 5. Again, I can’t seem to pin down exactly what is causing it, but it is happening.
