>Yes, in pretty any other set of controls, but not in VFP's combo. It doesn't react to the mouse wheel when the mouse is over the dropdown. It does when it's over the textbox part. It's a behavior which annoys me since VFP5 and I've sort of given up hope that it will ever be fixed.
Actually it does in the very few cases I use combos, and I don't recall having done anything special to get it working. On the other hand, I don't allow any editing in the combo. I always use Style = 2, Dropdown List.
