      Description

      FULL PRODUCT VERSION :
      1.5.0_06

      ADDITIONAL OS VERSION INFORMATION :
      WinXP SP2

      A DESCRIPTION OF THE PROBLEM :
      Access the following URL using Mozilla Firefox 1.5 under WinXP:

      http://www.webbased.co.uk/mca/mozcrash/

      While the applet is loading, keep moving the mouse in quick circles over the area of the applet until the crash occurs.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Applet uses a MouseMotionListener to track the current mouse position and feeds it back to the web page using LiveConnect. The best way to trigger the crash is to go to the above URL (note applet is signed because it downloads a test image from our server) and while the applet is loading, keep moving the mouse in quick circles over the area of the applet until the crash occurs.

      Note that while this is a simplified version of our actual production applet, the crash can occur randomly in our production applet when the mouse is moved whilst loading a different image into the viewer. This code is a simple implementation of a viewer using ERM's ECW technology (www.earthetc.com).


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      No crash.
      ACTUAL -
      Crash which invokes the Mozilla Talkback agent.

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      (none)

      REPRODUCIBILITY :
      This bug can be reproduced always.
