Well, if it were me, I would do a little research and find out if the attorney got paid. That would explain the lackluster attitude. But, it also seems to me that the other party would want this settled ASAP, and so by not cashing the check, are you not accepting the settlement? Perhaps you have legal recourse to take them back to court and get his name off the settlement? Another thing to find out, IMO. Also, with all this research to do, you should be sufficiently occupied to keep your mind off trying to get AH to "see the light."
