I have also noticed that on many menus and functions (even volume), including Hijack's menus, rotation of the knob at speeds above "carefully" results in unpredicable increments, and those increments can be in the desired direction of knob rotation, or annoyingly in reverse direction of what "should" be happening for the curent direction of rotation.
And at times it will seem to "stick" at one value, and will only unstick (and continue to increment/decrement the setting) after rotating the knob in the opposite direction a fair number of clicks.
This might be a hardware encoder problem (flakey component), or something in the software decoding of the knob rotation input data.
I am now using 2.00 Beta11 with Hijack 275, have not used the older empeg versions much (Beta7 for a little while). Have updated Hijack numerous times.
Hmmm... Using one of my player's knobs just now, it seems fine.
I wonder if I am recalling experiences using an earlier Hijack version, or if I was just imagining the problem...:
