I cannot eject my portable SSD with OC running, even if it is put into background. I need exit the app to use "Eject Media" to eject the SSD.

From event viewer:
The application \Device\HarddiskVolume4\OneCommander\OneCommander.exe with process id 5056 stopped the removal or ejection for the device USB\VID_0BDA&PID_9210\MSFT30062615878209.
Process command line: "D:\OneCommander\OneCommander.exe" -nowindow
List of affected devices:
STORAGE\Volume\{ba315ea8-d865-11f0-b5e4-88093502c8ab}#0000000000100000

My OC version is the latest; Windows 11 26100.7623

I have improvements on this in v4beta, but make sure you switch to a folder on different disk on any pane/window (even hidden) that is displaying content of that disk, as watching for folder changes or getting folder sizes/thumbs in each open pane prevents ejecting the disk. Windows doesn't even mark external disks properly as "Removable" so this needed several workarounds that won't be coming to v3
