More testing...
Some of my machines haven't got Qt5, so I have both the latest version of Calibre and 1.48.0 available on the stick:
inside, both calibre_qt4 and calibre_qt5 are similar (the only difference is the version of calibre in calibre folder):
Both symlink to the same library on the stick.
All works fine for both and I am very happy. apart from some messages when closing older version:
