309: Octave lines (ottava, 8va) do not play back correctly

Due to a minor problem in Sibelius 2.1, octave lines (also called ottava lines, or 8va lines) do not play back correctly.

These lines play back correctly except for the last bar over which they extend; e.g. if an 8va line extends over four bars, the first three bars will play back one octave higher than written, but the fourth bar will play back at the written pitch.

This problem is fixed in the free Sibelius 2.11 update, which can be downloaded here.
