Exception thrown - 2nd monitor

Hi all,
           The exception shown below is thrown when I open a JFrame with a
visad display on my 1st monitor, then drag it to my 2nd monitor and click a
button to open a JDialog with another visad display in it.
I've attached a small sample program that demonstrates this, so to try and
repeat the bug:
Run the program
Drag the JFrame to your second monitor (you'll obviously need a dual head
display)
Click the Open JDialog button
  And you should get an exception!!!

An exception was thrown on 2 windows machines with Matrox DualHead graphics
cards
and also a Linux machine with a dual head nvidia graphics card.

Not sure if this is VisAD or Java3D, hoping someone could shed some light on
the cause...

Cheers,
Scott Anderson
