OPERATING SYSTEM(S):
Redhat Enterprise Linux AS version 4(RHEL4), and RHEL4+Update1

FULL JDK VERSION(S):
java version "1.5.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode)

DESCRIPTION:
Steps to Recreate:
1. Download these input method tools.
http://java.sun.com/products/jfc/tsc/articles/InputMethod/InputMethodHotKey.jar
http://java.sun.com/j2se/1.5.0/docs/guide/imf/spi-sample/CityIM.jar

2. Launch InputMethodHotKey.jar and define a hot key combination. such as Shift+F4
$ java -jar InputMethodHotKey.jar

3. Install CityIM.jar into jdk/jre/lib/ext directory.

4. Launch JTextArea with Motif Toolkit. For example, notepad demo (demo/jfc/Notepad/Notepad.jar).
$ AWT_TOOLKIT=MToolkit java -jar Notepad.jar

5. Press the key combination you chosen in step 2, and choose City Input Method.
    Any language of CityIM can recreate the problem.

6. Type "tyo" and press space key twice to invoke the lookup window

Result:
CityIM's input window and lookup window appears under the application window.
Then, we cannot see anything at the time.

Expected Result:
CityIM's window should appear over the application window.

Additional Information:
On RHEL4(GNOME), both 1.4.2 and 5.0 can recreate the problem.
But, RHEL4(KDE), RHEL3(GNOME,KDE) and SLES9(GNOME,KDE) cannot.

This problem doesn't occur with XAWT.
