I'm working on a mobile project. I created a spark List, which item renderer is an extension of ItemRenderer. Each of my item renderer contains one spark Image, one Label and a number of small buttons which varies from 3 to 20. Now, scrolling the list is terribly slow. There are ways to improve scroll speed? I spent a lot of time but without success. Regards federico
