Sometimes there is another thread that is making a communication process. But generally I dont have other threads running.

I calculate the most of it before hand. We are working with components, so inside the painting method there are some calls to the component`s methods in order to paint themselves.

>When you say you are doing a "full screen" drawing, what kinda of stuff are you doing, is it painting an image, or drawing points, or a single gfx.fillRect(x,y,x1,y1); ?

We paint using fillRect, drawRect, etc. directly to the Graphics instance of the screen.
