Music info (mi) slow to update. Different to editor window

Since updating v3.30 I've noticed that mi functions are slow to update. For example when I commence playing a track mi(artist) returns "unknown artist" for sometimes up to 30 seconds.

Additionally in the KLWP editor window what is displayed in the mi fields is different to what is on the homescreen. In that sometimes the homescreen will update but the editor window will not. If working with mi(title) this will sometimes return blank, so you can't position text in the editor as you can't see it. Or if the track has changed the homescreen will display the current playing track, but the editor will show the previous track.
