YES, that solves the issue. Smart of KER only to calculate what is needed :-) makes me appreciate it even more. Seems at least one Display-bit of KER wich deals with manouver-nodes has to be active. Having an orbit window with only e.g. time to periapsis doesn't update the KAC times. And it doesn't matter where that calculation takes place. If the value is displayed in the surface window that works, too. So TriggerAu: maybe add at least a tooltip, or better a warning that prompts to activate and show at least one manouver-node related piece of data in any active KER window. (and verify that all man-node stuff is calculated if at least one is activated. I didn't test this very thoroughly) And thanks, Tarheel1999.

The integration with KER doesn't seem to work for me. KAC always says "Enough \Delta v: False" even though I have a single stage with more than enough delta v. KAC v 3.4.0.0 KER v 1.0.18.0 If you need more input let me know.
