With some combination of Windos, IME, and JDK version,
IME language bar becomes to flicker.


1. Reproduce

 1) Install MS IME2002 and jre1.3.1_01a
 2) Compile the attached sample code, Applet2.java
 3) Invoke the attached Applet1.html
    (ex. By double clicking the above file)
    -> you can see a textfied which has "JTextField" in browser window.

 4) Move the cursor to Textfield and click
    -> You can see the caret start to blink

 5) Please keep looking the IME language bar
    Then the bar blink periodically.


2. Configration
 
  - MPU : Pentium IV 1.4[GHz]
  - Mem : 384[MB]
  - OS : WindowsXP (Japanese)
  - IME : IME2002(Japanese)
  - Graphic Card : Win Fast geForceII MX SH pro
  - JRE : JRE 1.3.1_01a

3. Note

  This behavior looks to depend on combination of OS, IME and Graphic Card.
  The licensee tried various cases.
  The followings are their report although I can not reproduce them.

  
 [Behavior]
    IME language bar blinks SYNCHRONIZING with the caret's flickering.

 [Configrations]
   1.FMV-6700TX4
     CPU : Pentium3 700MHz
     OS : Windows2000 + IME2002
     Mem : 128MB
     G. Card: ATI Rage128 GL 4X (AGP4X)

   2.FMV-610GTX6
     CPU : Pentium3 1GHz
     OS : WindowsXP
     Mem : 512MB
     G. Card: ATI Rage128 GL 4X (AGP4X)

   3.FMV-610GTX6
     CPU : AMD-K6(R)-2 300MHz
     OS : WindowsXP
     Mem : 64MB
     G. Card: ATI 3D Rage PRO AGP 2X

  [Result]
    - When some Swing components are used, this seems to happen.
      However, this does not happen to the Swing components on "Frame,
      only on "Applet" like the sample code.
    - This happens not only with Java Plug-in 1.3.1_01a, but also
      1.3.0fcs and 1.4.0rc-b86.
    - This does not happen with "Tridend Cyber9525DVD PCI/AGP".
