Less to do with .24, but since it happened there ... First Minmus flyby. Gathered high orbit science (let's hear it for the "science bomb!"). Ready for your EVA, Jeb? As soon as he exited, he let go. Dude! Why? I spend 30 frustrating minutes learning to use suit RCS. Never got really proficient, but managed to get him plenty close, yet he wouldn't get back in. I never get the bleeping [F] Grab prompt, even though he's hugging the hatch. Mashed F anyway, no joy. Turns out that a light over the hatch will not obstruct an EVA, but will shove your little Kerbal off immediately. Additionally, the position of the light will prevent your little green friend from getting close enough to the hatch. I suspected the first part, then confirmed it with a pad launch. Always test your EVA from the pad when trying new part configuration on the capsule.
