jog wheel (Artist 6)

when I stop playback and then use the jog wheel to select an exact spot for editing, the cursor often (not always, though) jumps to some other position, not exactly where I stopped. how can I avoid this? does it matter where you click on the jog wheel? usually I do it on the little black dot, but it doesn’t really seem to make any difference.

nobody out there who uses the jog wheel when editing audio?
