Slider in sound mode showing blue not pink to start

Slider in sound mode showing blue not pink to start - then as soon as it is used, it fills in pink

This has been fixed and patched in ZIM 019 - it was because the starting value of a Slider with vertical set was being read as its min rather than its max as intended - we have put a BREAK note in the Changes and updated the docs. It is unlikely that the change will break existing apps as soon as the slider is used the value is correct. We have not noticed the issue for the life of the Slider.
