Rating from the MR's main panel, rates the wrong track.
Steps: Select a track in MM NowPlaying list pane. This track is displayed in MR's main panel. Right-click and change specified MR rating.
Result: New rating is applied to first selected track in MM Tracklist (which is different).
The problem is that when clicking on MR panel, the focus is lost in MM, so it defaults to main Tracklist. Behaviour is the same as: select a track in NowPlaying list, click an empty area on MR panel, then press F5.
Do you think it can be fixed so MR remembers the focus state?
Anyway, forewarned is forearmed!
