Hi, I just started using processing and begun from the tutorials. The code in " Getting Started" runs fine. However, I have problems with " Overview".

I have ubuntu 9.10, amd64 and installed processing 1.2.1 (unzip in my a dir under my home).

In " Overview" I can run the first example

1.  line(15, 25, 70, 90);

but for all the rest I have the following problem. When I hit "run" the monitor starts flickering and X doens't respond (I can only kill X).

I tried to find a minimal example that doens't work, so I took the final example from "Hello mouse" section.

1. void setup() {
     // with X=480 (as well as smaller sizes) and Y size >- 125
     // monitor flickrs, X crashes
     // with this, everything is ok
     size(480, 120);
   
     // without this monitor flickrs, X crashes
     smooth();
   }
            
   void draw() {
     stroke(255);
     line(150, 25, mouseX, mouseY);
   }
      
   void mousePressed() {
     background(192, 64, 0);
   }
   

The strange thing is that:

1. Without smooth(); X crashes
2. with size(480, Y) where Y>=120 X also crashes

Do you know how to find what is wrong? If you need any more information let me know
