FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]
A DESCRIPTION OF THE PROBLEM :
When a menu is clicked after dismissing a modal dialog, the menu pops up, but vanishes before a menu item can be selected. Run my test case under Windows XP and follow the instruction that it gives you.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run my sample testcase. Select the "File->Select..." menu item.
A dialog will pop up with a single button. Press that button, then
you will see another dialog pop up. Press "OK" on the second dialog. This
will dismiss both dialogs. Then click the "File" menu again (releasing the
mouse). The menu pops up as expected. Now attempt to select an item. It
will vanish before an item can be selected.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect that once a menu is clicked, it should stay up long enough for a menu item to be selected.
ACTUAL -
The menu is displayed after it is clicked, but vanishes before a menu item can be selected.
REPRODUCIBILITY :
This bug can be reproduced always.

f.show();
}
}
---------- END SOURCE ----------
CUSTOMER SUBMITTED WORKAROUND :
When selecting the menu, don't release the mouse, or else click it twice.
Release Regression From : 1.3.1_08
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
