The software does not execute the turns of the key lines of the ritornelos.

The execution measure 1570, where the ritornello begins, to measure 1585, where the final ritornello is located together with the first switch back, the program does not execute the jump to the second switch. The same error occurs just below the bars 1587 to 1602, where again the ritornello is executed correctly, but without executing the jumps from the first to the second return switch. And these errors are repeated until the end of the document. These two examples can be found on page 25.

The songs edited before the mentioned ones, are not with this error, this appeared suddenly without the user having made any change in the software or in the mentioned file.
