ADDITIONAL OS VERSION INFORMATION :
Linux localhost 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 i686 i386 GNU/Linux
EXTRA RELEVANT SYSTEM CONFIGURATION :
Red Hat 9.0
libgnome-2.2.0.1-8
XFree86-4.3.0-2
A DESCRIPTION OF THE PROBLEM :
When I move the window it maximizes almost everytime. Only happens when enabled Java Look&Feel at the beginning. Doesn't happen when I hava Java L&F but native titlebar. Doesn't happen with 1.42 but happens with 1.5 beta1, 1.5 rc1 and 1.5.
I have test many Sun's examples and happens in all of them.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Click on titlebar an move the window (must have Java Look&Feel decorated titlebar). Sometimes doesn't happen if you move it to screen borders.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Window must not maximize, only move.
ACTUAL -
Window maximize.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error messages.
REPRODUCIBILITY :
This bug can be reproduced often.

CUSTOMER SUBMITTED WORKAROUND :
If I enable Java L&F after invoke JFrame and i got GNOME's titlebar the frame acts normally.
Release Regression From : 1.4.2
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
