Hello
It used to be that Flipping a component using the Mirror in the
Schematic Editor simply reversed the symbol and text origins but left
all the text reading the right way round. (where as the Layout editor
would correctly reverse the text for the under side of the board).
In V6.1 the actual text in the Schematic is mirrored (i.e. printed up
side down).
Regards
