well, that is some extreme lifting goin on there feller. I have to say i have not quite seen it that extreme before. However, i experience the same problem somewhat, though to a far lesser degree (fortunately). It is my pinky, like you, and it is raising up, but it only seems to raise when i am doing structured speed exercises. Maybe raises up about 3/4 of an inch or a little less whereas my other fingers stay close to the strings. I find, however, that all of this has improved by practicing scales religiously in the form of improvisation, working all up and down the fretboard, all of my fingers have gotten MUCH closer to the strings. My pinky is still inaccurate though, relative to the other fingers which poses a problem for sure.
As i am typing this, i just realized the the pinky on my left hand, out of habit, does not even really touch the keys except to used the shift button. :? Some things clearly need to be fixed! :x
