After installing RealChute for the first time, I see no actions in the Action Group window for a chute added to my ship. The chute is listed, but no e.g. "Arm" action. And probably related to this, I see no way to open the Parachute Editor window. Clicking the chute name in the Action Group window does nothing. I've tried this on a new Sandbox game with no luck, as well as an existing save. What did I do wrong? RealChute v1.2.4 (never before installed) KSP v0.24.0 (is 0.24.2 required?) Thanks. Happy to post logs if it's not something obvious.
