I'm not observing this problem -- next and prev go through precisely the
same operations, and the callback doesn't come from them. (It's actually
a "frame change callback" that has nothing really to do specifically
with "animation.") So I'd be surprised if this is the case. Note that if
you are at the end of the range and you issue a frame change that does
not have any effect, no callback is made.

I have checked in changes for 11.1.45 that add two more parameters to
the frame callback:
function animFrameCallback(frameNo, fileNo, modelNo, firstNo, lastNo,
isAnimationRunning, animationDirection, currentDirection)
animationDirection is what changes with "animation direction -1" or
"animation direction +1"
currentDirection is what changes with "anim playrev" and when the
animation starts going backward in "anim mode palindrome"
so the PRODUCT of these two numbers indicates the "true" direction of
the animation.
Note that firstNo and lastNo are numbers that encode the file and model
as "file*100+model"

That's not a bug. "SHIFT" does just that -- shifts the arrow around;
"ALT" does the altering of the shape. So use alt-left-click if you want
to alter the shape of the arrow.
