JDK-4136103 - JApplet repaint/deadlock problems
Description

Name: sg39081			Date: 03/25/98


Steps to reproduce the problem:
  Create an applet (mix of AWT and Swing 1.0.1)
  and expand/collapse tree nodes, select table
  rows, select items from menu, click on buttons.
  After a varying amount of time, the applet stops
  repainting. The only way to repaint is to min/max
  the frame (the applet has dialogs & frames) or to
  move another window on top of the frame.
