Regression: Navigation is suspended if the screen is locked.

This means no navigation with N900 in pocket (e.g. cycling) because of spurious screen presses.
And no energy saving by navigating voice-only.

Sygic fixed this with an update to v9, now they've broken it again.

The interface is certainly snappier that the first v10, but still lagging behind v9 in terms of usefulness (for me) because of this issue.
