FULL PRODUCT VERSION :
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

FULL OS VERSION :
Windows NT Version 4.0

A DESCRIPTION OF THE PROBLEM :
We have a print preview dialog which is a JDialog. You can launch a print dialog from the dialog. Print Preview is a modal dialog. The PrinterJob.printDialog() method is called from a separate thread for obvious awt / swing EDT problems. The printDialog when cancelled tries to put the focus back on the main frame again. Ordinarily this should have the effect of putting the focus back on the modal dialog of the main frame. You can then use shortcut keys and accelearators associated with the menu on your mainframe even though you have a modal dialog open. All mouse clicks etc etc are ignored on the main frame.
On my application I actually get this to reproduce when requesting focus on the modal dialog even but I could not reproduce this on the sample below.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Follow source below
Click file open
Then click Test button
Then click cancel.
Click on the main frame again.
Click on Alt + f

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
This is a frame with a modal dialog.
Nothing should happen
ACTUAL -
The menuitem appears.

REPRODUCIBILITY :
This bug can be reproduced always.
