Thanks Anton for your response. I understand very well your explanation : as you add more and more draw commands in the effect block as it slows to draw the entire block. but if you try the sample code i posted you can see that you can draw for a very long time and very fast with a pen that follows mouse very closely. Then start again the script, click one time immediately to draw a circle and move the mouse fast, so you can see immediately that the drawing performance decrease.
Your suggestion is a good idea to resolve this problem but i'm really surprise by the result of my test and i can't believe that drawing a simple circle (just one!) is so consequent. Or i must understand that in rebol drawing a circle is very complex and requiere a lot of compute that slow down performances. Maybe someone have another explanation to solve this question.
