Below-spot input method's composition area is not usable due to the rapid focus changes

1. Setup City Input Method (obtain from & refer to: http://java.sun.com/j2se/1.5.0/docs/guide/imf/spi-tutorial.html#Sample%20Code )
And setup the HotKey using HotKey.jar, which is also available above site (eg. Ctrl+F5 )
2. Start Notepad demo using below-the-spot option:
   %java -Djava.awt.im.style=below-the-spot -jar Notepad.jar
3. After Notepad appears, turn on the City Input Method (eg. Ctrl+F5)

Then you'll see that the composition area of input method appears on top of the Notepad (correct behavior), but the focus changes rapidly between the composition area and Notepad, which makes impossible for the user to type in the composition area.

Since there is no change for IM, I'm categorizing this issue under awt.
This issue is only seen on CDE.
Using JDS, it works properly.
