The above is no longer true! I treated myself to some new modules last
week, including the A-123. My initial reaction is that the A-123
behaves in pretty much the same fashion as the A-121, and in fact
could be slightly worse. I haven't really had time to check it out
properly though, I'll try and do so over the weekend, and then I'll
report back!
