Planner isn't compatible with TheSky X. Planner uses a bunch of "scripted operation" calls of TheSKy 6. The corresponding ones in TheSky X aren't quite ready for prime time. For the time being, you'll have to add targets in Planner by right-clicking in the target list and filling in the info manually by reading the info off TheSky X display. I do hope to get Planner to work with TheSky X soon.
