Processing 1.0.9 on Ubuntu 9.10

This piece of code:

width = 640;
height = 360;
//size(width,height);
background(0);
print(width);

produces a window with the size defined in width an height but the sketch
size inside the window appears only on 100 by 100px.

Not really sure that's a feature.

Un-commenting the size() function doesn't solve the problem.

Never assign width and height, only use the size() command. And the size()
command must always be the first line in setup().
