Copy and paste of plain text (unformatted text) between non-contained notepad.exe and contained notepad.exe does work.
However, copy and paste of graphical data between non-contained mspaint.exe and contained mspaint.exe does not work.
Also copy and paste between non-contained and contained write.exe doesn’t work either (selecting paste special and choosing unformatted text does work).
Seemingly it is only possible to copy and paste plain text (unformatted text) between a contained and a non-contained application, other clipboard formats do not work.
Clipboard function usage between a contained and a non-contained application is rather limited this way.
