Sorted, With a little help from Ninja Monkey
This is actually a very good feature, but perhaps the default 15secs is a little too severe.

@Guino I'm sure you are aware by now that our problem is solved, as below.

Sorry for any thread jacking. But this could be of interest to anyone who thought this was a RR problem.

Anyway, to turn it off: open Settings.ini inside the Map Monkey folder, change the line ManeuverRepeatTimeout=15 to ManeuverRepeatTimeout=0
