[TC9.51] Background Copy/Move freezes main window

[howl196]

Hi.
This may not be an error in the strict sense, but since I encounter it regularly, I report it here.

Whenever I move (as a background operation/F2) many folders from a network drive, the main window remains frozen/is not responding until all folders are added to the list. This causes a long delay before I can enter a new folder to select and add sub-folders to the list.

Can this be changed?

Regards,
Jens
