Playback does not follow mixer patch
In attached score, after initial loading, all parts played a piano sound, at full strength.
When I changed a patch to something else and then back, the right instrument sounded. To get the strength where it should be, I had to manipulate the controls back and forth.
This is the first time I noticed this behaviour. I just installed the latest version, may be a regression issue.
