There are time I want to advance a maneuver node's burn time many orbits into the future. But I'm have two crazy problems with the UI. 1) Every other time I click the button, the maneuver node "closes" forcing me to re-select it, then right click it to get back to the advance-orbit-button. 2) I also get a ton of popup's to select various targets, as though I were clicking on them or empty space, as opposed to a button. These popups appear over the manuver node controls, and often gets clicked accidentally. My workaround for this, which wont always help, is to orient my view such that a small section of the button remains visible behind any other popups (but this doesn't always work). I'd like to be able to click the advance-orbit-button a few dozen times in a row, without pulling my hair out. Does anyone have a way to work around this UI oddness? Also looking for any suggestions on how to advance a maneuver node a huge number of orbits, like in the hundreds, without clicking hundred of times.
