Despite the hints earlier in this thread, I still cannot solve either of the second parts of the 11th across and down clues. In my grid there do not seem to be any spaces for more across entries, so I am assuming that both are down entries. The only available spaces in my grid appear to be in the fifth and eighth columns where could accommodate SEN and AAH. The latter is hidden in the down clue, but the former is nowhere to be found. Clearly, I am barking up the wrong tree. any hints gratefully accepted.
