I'm a newbie and I'm having trouble getting Room to Maneuver to work for me. I have version 1.8.0.2686. After launching, I click the new (Ver 1.7) Maneuver Mode button below the staging display. I see values for Apoasis and Periapsis, but only see "LOCKED" where the "Room to Maneuver" video indicates I should see a "Time To" value. This is also true before I launch.
Is there something I'm doing wrong, not doing something I should be doing or do I need more science (I'm at 34), etc.
Everything about KSP has been great and I'm really liking what I've seen so far.
Thanks.
