When did the buttons in the dialog boxes get moved? I have just upgraded and the buttons have moved. This is a disaster ! I have been using calibre for so long that I do not look at the buttons but automatically put the mouse in the right place! No graphical User Interface that I have ever used ( and I have been involved with computers for over 40 years) has had the OK button on the left, it is ALWAYS the rightmost button. All the UI standards and design advice is to put the affirmative button on the right and the most negative on the left. Please change back to the correct positioning ASAP
