Here is an experiment:
(1) On a Vista machine that is NOT a laptop, log in as a regular user (not administrator).
(2) Open the web site https://jogl-demos.dev.java.net/applettest.html
(answer “no”, or if you like you can answer “yes”)
(4) Drag the browser window around and see if the gears stay with the window.
This should tell us where the problem is.
Any takers?
