Zoom recalculating

The following is happening with almost every chart I open:-

  • I open a chart and press + to increase the zoom or press the ↔ fullscreen button, perfect
  • The chart will suddently reduce zoom to its default value, so I have to re-adjust the zoom again

The earlier problem has been resolved of chart zoom not being saved when you change between charts, but this recalculation is very time-consuming as well.

I also notice that, on the main map page, where you have your route, very often just pressing somewhere on the screen will cause the zoom to increase, also consumes time as you then have to reset the correct zoom again
