Player will not stop UPDATING USB

After clicking on the USB music folder and then “update”, the update animation never stops, and restarting the web browser doesn’t cure the problem.
After 3-4 minutes the files show up (975 songs) and play but the web interface is slow and playlists don’t work.
Anyone run into this?
