Shaboom: after you fire up the config, there should be a key binding option available in the main wow menu for the frame finder, bind it to a key and use it to get the frame names
Yes, as I said I wasn't in game at the time of my previous reply :)
Target frame gives PitBullUnitFrame2
Target of Target frame gives PitBullUnitFrame3
I should imagine this is because as a non pet class I have both the pet frame and pet target frame disabled, that's probably why our frames give different IDs Seerah.
