This problem is seen only with dual-monitor systems running Windows XP with remote desktop enabled. It also happens on machines with two video cards, not
on machines that have a single video card that feeds two different monitors.
It happens under JDK 1.4.1_02, 1.4.1_03 and 1.4.2_01.


STEPS TO REPRODUCE:

- Choose any Swing/AWT application (like: SwingSet demo)

- Set the monitor on the right to be the primary display (normally the left
  monitor is the primary).

- Log into the machine through remote desktop.

- Launch the application (any Swing app should cause the behavior as
  well).

- Disconnect the remote desktop session, but do not log out - the app should
  remain running.

- Log in to the machine locally.

Most of the time the VM hits this exception:
