yes, the same thing happens every time time people change keyboards, regular as clockwork, and the same answer has to be given. They actually complain that the style is not the same, perhaps not thinking through that this argument would mean that all the styles would never change on a new board if they wanted them all the same as those on the old board! If you follow the advice on page 21 of the book you can't go wrong.
Personally I identify the duplications before I save all the previous styles, Bill, because this saves a lot of work.
