>>Hi,

>>>When you scroll down does this occur when you scroll fast and slow? I've got a similar problem with a list box. If the user clicks on the down arrow of the scrollbar repetively, no problem. But if he clicks and holds the mouse down causing the listbox to scroll quickly, when it reaches the bottom it becomes visually messed up -- similar to what you've described. I'm using 5.0 as well. I've resigned the fact that it is probably a GUI bug and hope it is fixed when I get the VFP version in Visual Studio.

It seems that when the list moves too fast, Fox doesn't have time to decide which records come next in the list. Just a guess...
A hint though- for the situations that I originally wanted a listbox for but couldn't because of this bug, I have constructed grids that look and work just like listboxes. Want incremental search in your grid? Use the ingrid control in the files section. Instead of the interactive change event, use the afterrowcolumnchange event. Works like a charm and you don't have to tell your users it's not your fault.
