I have a different problem related (I think) to thumbnail caching for the library views (thumbnail array, thumbnail list). If I load a batch of albums into MC's main library, and then connect using JRemote, all is fine. If I delete everything from the main library in MC, and then delete everything from the "Removed database" smartlist, and close MC (and JRemote) MC starts with a clean slate when I reopen it. If I then connect again using JRemote, however, even after having closed it first, many if not all of the cover thumbnails from the first version of the library remain visible in the library views along with the new albums. But the album names only reflect the new library contents, so the wrong thumbnails are associated with a given album name.
The thumbnail associated with each album in "Playing now" remains correct, as do the thumbnails for each track. I have embedded the thumbnail image in the tag for each track (file) as well as including a "folder.jpg" copy in the album's folder.
So I think the simple solution would be a way to flush the cache in JRemote so it wouldn't get confused, but I can't find one and I'm open to any suggestions. It's odd that the discrepancy occurs only in JRemote while all is as expected in MC.
Thanks in advance for any insight.
