Hello,

I am running an application with a JFrame that displays some Java Swing
components, as well as 4 separate Canvas 3d objects, each of which contains
a Java3d scene graph.  I've noticed an intermittent problem with the
initial display of this frame in that sometimes the application freezes up
when the screen is initially displayed.  When the freeze occurs, all of the
Swing components are displayed but the canvases are blank.

I've done some debugging of the problem and it appears to occur when the
setVisible() call is made to display the screen for the first time.  I
haven't been able to isolate this issue any further than that, but my guess
is that there is some sort of deadlock occurring between Swing and Java3d.
Has anyone ever encountered this problem before with multiple 3d canvases
in a Swing GUI?   Any suggestions for a workaround would be greatly
appreciated.

Thanks,
Kristine
