Try specifying -Dsun.java2d.noddraw=true on the command prompt.
Please follow up indicating whether this solves the problem.

The window decorations can be disabled as of 1.4 and above; see
the sources for the Grand Canyon demo
(http://java.sun.com/products/jfc/tsc/articles/jcanyon/) for an
example. I spent some time in the 1.4 timeframe trying to
understand exactly what Windows API calls go into making a
full-screen window which is compatible with OpenGL; this is the
underlying implementation of full-screen when
-Dsun.java2d.noddraw=true is specified. However, I believe there
are still problems with this implementation though I haven't had
time to look into them. If you or anyone else can write a small,
self-contained C/C++ program on Windows (not using GLUT) which
makes a full-screen OpenGL window and draws a triangle into it,
I'll try to get the non-DirectDraw full-screen implementation
fixed in the JDK.

FYI, the SCSL sources for 1.4 are available on Sun's web site, so
you can look at the current full-screen implementation.

Well, I get the window full screen, and the gears the full size of the window, but the window still has borders and things, and the bottom appears behind the taskbar... and we have no 3D effect still. :(

Maybe if the Frame object used to hold this stuff was a Window object instead (which as I recall, has no borders or widgets or anything)... but I'm not sure how to go about altering it to do that, since the API docs say Window objects need to have a parent Frame.
