In an Impress presentation I have a sound file which is activated by a slide transition and plays across several slides. It works fine, playing through several slides with a ‘no sound’ transition, until it reaches a slide with the transition ‘stop previous sound’ and it stops. So far so good.
However, if while the sound is playing I try to move to the previous slide (page up, left arrow, backspace etc) the program advances to the next slide instead. After the ‘stop previous sound’, the slide changes revert to the expected behaviour. Although this seems quite clever (to know that a ‘no sound’ transition is irreversible while a sound is playing), it is sometimes annoying.
Can I do anything to ensure that ‘previous’ means previous?
