That was my fault, I didn't really make that obvious, now that I look at the original post. The tone of voice that I use in my head when typing doesn't always show up in print (I haven't learned the html for that, yet).
I guess what I'm doing is free lunging, according to Hair.
Written text is always cold... lots of misunderstandings happen that wouldn't happen in person!
Followup.... sometimes it is necessary to actually push her (at the neck or shoulder) out again if they have come in to you.... but the key is to not pet or comfort them at this point, you can push, soothe with low voice if necessary if she is really flustered and confused, but you don't want to reward it. After she moves forward and you have praised that with happy 'good' sounds, and before she can stop or screw up again, ASK for the WOAH, and reward her with a rub and a pat only then.
I'm no lunging expert, but in certain training methods, if you "address" the hind quarters with the whip, that means to stop, turn and face. Try addressing her inside shoulder while remaining behind the drive line to see if she reacts any differently.
