fpGUI's StringGrid doesn't have any delay on scrolling or jumping to the extreme limits of the data. The all appear instantly. My point was that NO application should display so much data to a end-user, as it is simply too much. A end-user always knows what they are looking for, more or less, (otherwise they wouldn't be in that screen). So present them with some filtering options first. Basic UI design principles... but this is another topic to discuss elsewhere.
