Hallo. I need a little help about an issue i found right now. I have a list with a custom itemrenderer and i scroll it with normal scrollbars. Everything works great but i don't understand 1 thing. When i scroll holding down the mouse, all the elements scroll correctly, but if i scroll with single mouse click, when i click for the "FIRST TIME" on the scrollbar, it steps only for 1 or 2 pixel... From the second click it finally scrolls each element (58 pixels)... Why there is this problem with the first click??.. How can i solve this problem?.. I hope you understand what i mean.
