I've recently come back to SSM after about 10 years, and I'm re-climbing the learning curve. I've got over a few problems, but this recent one I can't solve at the moment. I've worked through a lot of SSM 51 A and reached the stage where I have the Westar -VI hovering over the Telestat - H doors. So, that's followed the COMM 1216 to "Manouver (US spelling accepted) EV 2 & position the Westar-VI, etc, etc." I guess I then expected COMM 1217 to come up "EV 1 & EV 2 - Use the RMS to grapple the Westar-VI satellite's front grapple", but that didn't happen. I tried "Timeslip" to see if something came up, but it didn't, so I just went ahead to try to grapple Westar-VI. I've spent about 8 + hours on trying to grapple, I get close but can't complete it. Is there a switch in the programme which hasn't been switched, or is there some secret I've missed? Any help would be gratefully received.
