Java2D application on J2SE 1.4.2_02 on Win XP on a dual-headed Workstation.
With certain graphics boards (Matrox G550, 450, 200, Radeon 7000 and more)
a deadlock occurs if windows are opened on both "heads". It can be reproduced
turning on a screenlock while windows are placed on both displays.
A testcase is available to reproduce the issue. See attachment for
Testcase and dumpfile.

The problem can't be reproduced on sparc systems, win2k systems or
single headed workstations.

steps to reproduce:

Start the app on WXP SP1 on a multi screen setup, move window in a way
that rectangle image is placed partly on screen #1 and partly on screen
#2. Lock/unlock the screen using ctrl-alt-delete, or, open a command
window and change to full screen mode and back via alt-enter (several
times).
