Intermittent JTable Selection Problem

Question

Hi,
Everyone once in a while, under NT with 1.4.x, I have problems selecting and highlighting row under JTable. It happens a good bit, but this does not happen all the time. When the table is buggy, it does not keep the row selected nor does it highlight the row. You may have the row selected on a mousedown, but once you release the mouse it's done.
Since this is happening for a variety of JTable's I didn't bother to send Java code. Has anyone else encountered this sort of thing? Or does anyone know what I should be looking at?
The intermittent part is what's killing me. It makes it hard to track down with any high degreee of confidence in the answers.
thanks for any input or suggestions,
Geoff

import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
public class Test extends JFrame {
  public Test() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container content = getContentPane();
    String[] head = {"One","Two","Three"};
    String[][] data = new String[40][3];
    for (int r=0; r<40; r++) {
      data[r] = new String[3];
      for (int c = 0; c < 3; c++) data[r][c] = "R" + r + "-C" + c;
    content.add(new JScrollPane(new JTable(data,head)));
    setSize(400, 400);
    show();
  public static void main(String args[]) { new Test(); }
}I've been clicking until my fingers bled. Can't see a problem.
