Up front - a minor thing.
3rd day : noticed that with one specific external USB drive, the volume label is not displayed.
All other external USB drives: no issues, just this one (driveletter U)
Disk properties shows an empty box.
Repeatedly tried entering a volume label there, but it won't stick, i.e. the box remains empty.
No difference after refreshing.
That is to say, within Opus and after 1st PC boot.
Windows Explorer does show the volume label correctly though.
Solution: Opus File Exit and relaunch - it will display the volume label for the rest of the time.
Opus 12.19.6
