Animation - Need way to avoid UI wipe off

I need to implement a network simulation animation with messages (icons) flowing back and forth between nodes (filloval). Each node is a thread behind the scenes and determines which message to send based on its state transition model.

Now everytime the window is minimized or some other window comes over my swing window, the part of the window overlapped becomes blank. The books say that I have to put in all the drawing code in paint() so that it will update itself whenever invoked automatically.

How can i do this - the state transition is per thread. Any ideas as to how I can avoid the system from wiping my UI when minimized or overlapped?

This is set up to compile and run in j2se 1.5
If using j2se 1.4 or earlier comment out the j2se 1.5 lines and uncomment the j2se 1.4 lines in the three areas of NetworkPanel, eg,

I agree. Here's the link:
