I've been trying to track down some performance issues on my machine and turned up some logging within MC and found that every time a song it queued for playing, we copy the cover art to the temp directory (C:\Documents and Settings\mike\application data\J River\Media Center 13\Temp )with a name of something similar to MP3 Image - 14636.jpg and also copy over the entire track info html code instead of using what is in the directory already.

Is this how this is supposed to work by default?
I was also having the high CPU issue with Auto Import turned on as well that other were reporting. I am not sure what option I need to turn off if analyze audio, build thumbnails, or get cover art was the culprit. Since I was not adding anything to my library, we should not have been running at 10-15% CPU or doing anything. I disabled all options except auto-import and it appears it is back to normal after a restart of MC.
