Andrew,

I won't be able to reply till after Wednesday..

I'm not sure what type of UI you are trying to achieve. If I've misunderstood what you are trying to accomplish I'm sorry. I'll throw out some ideas anyway. *s*

When you say MoverBar do you mean the Thumb in the scrollbar part of the cbo? Or do you mean the higlight bar that shows the current choice? I don't think there are any detectable events that fire as the list is scrolled with the thumb. Turn on event logging and see what happens. You can use the InteractiveChange to do the record nav and Refresh() call, but that will only fire as the user keyboards through items or clicks to highlight them. It will also depend on what the RowSource of the cbo is. Using Alias is going to cause table navigation on it's own, using an Array or AddItem list you have to doo the seeks etc.

Which record do you choose to display as they scroll to a part of the list and the highlight is not visible? It may not be clear to the user either. I suspect this type UI would be real sluggish. I think the user would be better served by only displaying the current highlighted choice, and you can do that with the InteractiveChange() event.
