I think the "directional aspect is not only unusual but key to this
problem. I removed the bottom cover and checked the levers. The
potentially suspect one is not blazingly quick and perhaps needs
cleaning but I don't think it's at all related to this problem.
I'll reiterate that with the camera pointing up or forward the wind
lever works normally 1000f the time. With the camera pointed down or
upside down the wind lever works 00f the time. If the wind lever will
not wind simply rotate camera to appropriate position and then it will
wind normally provided you first release any pressure on the lever.
I also discovered that, if the camera is pointed up, the wind lever will
wind normally but the lever will only return half way before it gets
blocked by something. Return camera to facing forward position and wind
lever will return the rest of the way.
The behavior is as though there's a small pin or screw floating around
inside which manages to block a gear or linkgage when it's in the right
position. However, I can't see any such thing with the bottom cover
removed which implies something at the top. Given the additional
problem of not being able to fully return the wind lever when the camera
is facing up it would seem that perhaps the detent mechanism that holds
the wind lever in the half cocked position is somehow involved. When
the wind lever won't return it is in exactly the half cocked position
where there is normally only a slight detent.
Have I made the first discovery of the "out of control detent mechanism"?

The "directional" aspect is unusual -- could also be that a spring is
unhooked. You might want to remove the bottom cover and look at the
short lever behind and next to the battery chamber -- it should have a
rather heavy, short spring hooked to it. It (the lever) works the black
lever that gets sticky (above). With the camera wound, the black lever
should move quickly when moved. If it's slow and sluggish, it's got to
be cleaned.
