I have a data entry for that is used for the comparison of two documents in separate memo fields. This is done with two editboxes of exactly the same dimensions. I am trying to get one editbox to scroll when the user scrolls the other. It appears that there is no event that fires when the user clicks the scrollbar besides the editbox mousedown, mouseup, and click events. I guess I could use these and come up with a really fragile kludge, but I would rather not. Has anyone tried this or have any suggestions?
