In the Mini Player, the rating process is not working as expected.
By default all my mp3s are rated with 1 star when I encode them.
Then when I play them, I rate them according to my taste.
In the Mini Player, I can't rate the currently played mp3 to 3 stars directly. I have to click on the 2nd star first, then it seems to unlock the rating editing, and then I can rate to whatever value.
Tested on last MB 3.0.5880, in the Narrow Layout and the Wide Layout.
I was a Winamp lover... until I discovered MusicBee! No other music player can beat it!
