Ok... I posted earlier about it, but I'll see if I can add a bit more. From the times that you get it turned to the proper place and then not getting on the elevator, I assume you know what the proper combination of the wheel is. So what you have to try to do is get it to the spot that is 2 turns before the right combination. Then hit enter twice... hopefully it will register both of them, and while it is doing those 2 turns, you have a bit of time to get on the elevator.
I don't think this is necessarily the right way to do this, but it worked for me. But then again, maybe it is the right way to do it. Who knows.
I read a post somewhere else - can't remember if it was in this forum or another one - where someone claimed to have pulled the lever and stopped the elevator from going all the way up. But I haven't been able to get that to work for me.
