Hello all, I am doing some smooth scrolling expriments. I use a step method in which I adjust the display. When I set stepTime to 0, the time between steps is still between 10 and 40 msces. During a scroll which takes 10 steps I see apx 1000 redraws of fairly simple Morphs. That is 100 redraws per step. When an average step takes apx. 20 msec this is 0.2 msec per redaw. Does this look normal, or should I hunt for flaws in my program? If this is the normal speed, then I cannot do animations in morphic, such that I get a new frame every 14 msec (70 Hz), at least not the way I am trying to do it. Another thing I cannot explain is the following: when I repeatedly call my step method from another method (putting a Delay between the calls), the display does not always update. I just see the end of the scroll, but not the steps in between. Only when I add a World displayWorld I see the intermediate scroll positions. However, when I call step from an explorer the Display updates just fine, without an explicit displayWorld. Why is that so? -- Martin
