Chris,

This isn't a problem of yours; it's a problem with the List Manager.
When determining if a click is off the end of a partial list, it kind
of skids to a stop. There are magic "dead" spots, as well as magic
"live" spots which you have very little control over. I remember that
one guy here tried for several days to program around them,
unsuccessfully.
