A DESCRIPTION OF THE REGRESSION :
due to some limitation on menu events, i was forced to create my own version of MenuBar and friends. All this worked in JDK1.4.

Then came along JDK1.5 . The menu bar is printed, but unfortunately the submenu's for each menu-item are just not displayed. This occures with both XToolkit, and MToolkit. As far as I can tell it has failed with all releases of JDK1.5.

Then there is JDK1.6 . The submenu's are back. Works with both MToolkit, and XToolkit. Unfortunately the size of the sub-menu text boxes are not the same size than that of jdk1.4 . In jdk1.4, the sub-menu;s are almost squaresh looking. JDK1.6 the boxes are distinctly rectangular and thin. I would like to compare with jdk1.5, but that has never worked.

So is this a reverse regression? ;-}

REPRODUCIBLE TESTCASE OR STEPS TO REPRODUCE:
1) run pgm
2) click on "This" ( a "1" should appear)
3) click on "is" ( a "2" should appear )
4) click on "a" ( a "3" should appear )
5) click on "test" ( a "4" should appear )

RELEASE LAST WORKED:
5.0 Update 1

RELEASE TEST FAILS:
mustang-beta

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect all the JDK's to perform similarily. With MToolkit, and Xtoolkit.

this is a Linux box, with fedora 4.
ACTUAL -
JDK1.4 - sub-menu's painted, and square.
JDK1.5 - no sub-menu's at all
JDK1.6 - Sub-menu's painted, but thin rectangular boxes.

OBSERVED APPLICATION IMPACT:
I really dont know how to ans this. I thought this would have been fixed some time ago in JDK1.5 .
