Owner Draw List Box Scrolling Problem - ?XP bug
-
I have noticed a "visual scrolling" problem with owner-draw list boxes (both mine and others) in XP. This occurs with both stand-alone list boxes and ones associated with a combo box. The problem occurs if the My Computer | Properties | Performance Options | Visual Effects | Smooth-scroll List Box option is checked. The animated scrolling generated by windows is okay unless you click on the scroll bar to generate page-up/page-down messages. With this, the scrolling animation visually appears to be going in the opposite direction as expected...but when the animation terminates, the appropriate update has occurred (e.g. the expected items are visual). This is quite obvious when the list box size is large enough and the items are different in appearance. This does not appear to occur with non owner-draw list boxes. I cannot find any reference to this bug but it is clearly reproducible. Is anyone aware of a fix?
