Before scrollingAfter scrolling

I create comboBox with these settings (from .rc file): COMBOBOX IDC_COMBO_NAME,6,24,96,30,CBS_DROPDOWNLIST | CBS_SORT | WS_VSCROLL | WS_TABSTOP

But when i open my combobox and try to scroll by mouse wheel : Content of combobox is scrolled, thumb of scrollbar - stay on the same place. The same behaviour when i press scrollbar's arrow controls.

How can i trace the reason of such behaviour and fix it. Or maybe it well-known problem and have solution.

When you created the combo box control in the resource editor, did you forget to size its height by dragging down on the arrow key? Can you post a picture of what your combo looks like at run time?
