I am at a loss as there appears to be nothing in NSMatrix or
NSScroller that would deal with this behavior.
Thanks for you comments.

I have an NSMatrix (sub-classed) of NSImage cells. I set the
appropriate tool tip for each cell.
When scrolling the matrix using the knob or scroll buttons the
tool tips are fine.
When scrolling the matrix using the wheel on the mouse the tool
tips are incorrect.
Touching the knob after scrolling with the mouse wheel brings the
tool tips back into sync.
Is there a method to call after the user scrolls the matrix with
the mouse wheel to bring everything back into sync?
I don't know if there is - a quick scan of the docs for the class
doesn't reveal anything, but I just tried this with an unsubclassed
NSMatrix, and it works fine. That would suggest that something in
your subclass is causing this.
Why are you subclassing? Typically I have found that custom
appearance/behaviour of an NSMatrix is achievable using custom
cells, rather than subclassing the matrix itself.
