Improved: The Configuration Editor now saves most of its state (window positions, open files, etc.) when closing and restores it when run again.

Fixed: The GUI for the Copy command was behaving incorrectly when channels were selected by number instead of name.
Fixed: When the processing caused delay (e.g. via Delay command), the remaining audio was not output when the input signal became silence (e.g. pausing a music player), but only when the silence ended.
Fixed: The checks for missing registry values in Configuration Editor/Configurator should now be sufficient to reanimate E-APO after an OS upgrade. Also the Configurator did not launch when accepting the question in the Configuration Editor with UAC enabled.
