Maybe I didn't explain fully
I have two Musicbee installations, on my desktop PC and on my laptop. Both were running 3.0.6014
On both of these I have an auto-playlist that, amongst others, picks up a selection tracks that have not been rated yet. Any non rated tracks that have been played twice are then picked up by a further playlist to remind me they have been played but not yet rated.
As such I rate tracks on an almost daily basis.
I do not normally routinely apply patches unless there has been a problem I've noticed, if it's not broke don't fix it was what I was always told.
Yesterday I decided as I had not patch Musicbee for a while so maybe I should so did this for the laptop which is now running 3.0.6104.
This was when I noted almost immediately that it was not accepting the a new rating on the right panel. On further experimenting I have noticed that the "bomb" only appears on the Now Playing window, on the normal Main window the rating stays greyed out.
This shows an unrated track
This shows the track as rated in the Main window but rating not showing on right panel
This shows same track in Now Playing window with the "bomb"
I realise it maybe caused by missing a few patches in between but dont fancy doing a re-install from scratch
