Yes, I wondered why they set it, too. It's quite mysterious. And as far as extending ADGGIR - have you looked at that code? They were good about making very little of it private or mx_internal (yes, I know I can get around the latter), but the bulk of it is done in commitProperties. So you'd be limited to just stuff you could take on to the end of the overridden function. Likely I'd just clone the unit and change the bit of code I was interested in.
