java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

use "setCursor" API to set up a busy cursor in a modal dialog.
When "Apply" button clicked, use "setCursor" to set up a "WAIT"
cursor, then execute a long task, after the task is finished, use
"setCursor" to set back to "DEFAULT" cursor.
In Solaris 2.7(x86), both jdk 1.3.1 and jdk 1.2.2 run well.
but in Windows NT 4.0, jdk1.2.2 is OK, jdk 1.3.1 is not OK.
After the cursor becomes an hourglass, use the mouse to move it out of
the dialog, then move it back, the "hourglass" never comes back.

Please compile and run the sample code.
1. javac test_dialog.java
2. javac test.java
3. java test
4. click OK button
5. click Apply button, cursor becomes hourglass
6. move cursor out of the dialog, then move cursor back,
   you see cursor keeps "arrow" shape, not hourglass
