ljcox, I don't understand what you say, because the main problem is that PNP transistor needs a base voltage of almost the same as emiter's to turn OFF. U8 can turn on Q3 by just putting its output low, but putting its output high (5V) may not be high enough to turn OFF Q3 (if it is not darlington), so adding a LED will make this even worse (4,2 V as maximun voltage, that is not enough to turn Q3 off).
Maybe I got something wrong, or maybe you just missed something?
