Animation problems Windows Vista Pro/ Shoes r646

[Axel Etzold]

Dear all,

I am having problems with "animate", for some time now ...
I want to draw an animation of  a circle that moves from a point A to B.
Trying to follow the example "follow.rb", I managed to draw start point, end point,
and many circles in between, but they all appear at once (so there's no impression
of movement). Now, out of  several hundred in-between positions, I tried to choose
20 consecutive,  and let Shoes draw them, and push the index further, draw the next 20 consecutive.
But I don't get anything: if I remove the clear -do line below, and keep animate, the application
crashes (A "Shoes doesn't work anymore"-window appears, on windows vista pro, shoes r646), if I put the
clear-do line in, I don't see anything at all...)
The app.draw command alone works.

.....
    i=0  
   size=10
    while i+20<all_circles.length   
        t20=all_circles[i...i+20]
      & nbsp; t20.each{|t|
        app.animate(12) do
          clear do
              app.draw(t[0],t[1],size)
          end
        end
        }
       i=i+1
     end


What's going wrong ?

Thank you for your help,

Best regards,

Axel
