Sun Java turns off Aero effects while active

    I went to a website today that required Java and I found out that IE no
    longer includes Java. The link that popped up sent me to a MS page that
    stated this. I installed Sun's Java VM and everything works OK. Now when I
    go to a website that requires this plug-in I receive a notice that my
    desktop has been changed to Windows Vista Basic. When I leave the webpage
    it converts back to Vista Aero.

    The following notes apply to use of this release on Windows Vista platforms.

    a.. On Windows Vista, there is a more restrictive sandbox for signed
    applets. A user has fewer privileges than if they were running on another
    Windows OS.


    On a Windows OS other than Windows Vista, when running a signed applet, a
    user is prompted with a security warning dialog box and must respond. If
    "Yes" is clicked, the applet will have AllPermissions to run on the user's
    machine. This includes permission to write/delete a file from the local
    disk.

    On a Windows Vista OS, this is no longer true. Instead, AllPermissions is
    limited to Java Applet scope, not Windows scope. Because a process running
    in IE has a low integrity level, it will not be able to write/delete a file
    from a medium/high integrity level directory.

    b.. A signed JNLP application can run only with medium integrity. Granting
    AllPermissions in a Java Web Start application only permits the Security
    Manager to allow operations that it would otherwise deny by throwing
    SecurityExceptions. It does not in any way elevate the permissions a user or
    a process has on the system.

    c.. Due to limitations of Windows Vista, Java Plugin will no longer be
    able to write any file into the jre/lib/ext directory from IE protected
    mode. Java plugin extension install will not work as it does on other
    Windows OS platforms.


    d.. On Windows Vista the use of DirectDraw for hardware acceleration is
    currently disabled by default because of incompatibilities with Vista's
    Desktop Window Manager.


    The -Dsun.java2d.noddraw=false property can be used to re-enable the use
    of the DirectDraw pipeline. However, this is not recommended due to
    rendering artifacts and performance problems. To also enable the Direct3D
    pipeline, a combination of the aforementioned flag and -Dsun.java2d.d3d=true
    should be used.

    I don't recommend (not that I am a person of influence) Beta 6 of Java
    Runtime Environment UNDER Vista. For some reason, with Beta 6 version (or
    rather Java 6 beta 2 version) I can't seem to open a "File Open Dialog"
    (Chooser) from my home-spun Java application in Vista. Reverting back to
    Java 5 runtime 6 or 8, the File Open (Chooser) Dialog works in Vista.

    I know I probably should report this to Sun, but I haven't looked at the
    console to see if there was a stack trace yet which I'd probably need if I
    were to submit something to Sun.

    Thank you, Colin.

    I had been using the other Java 6 beta. It worked but
    was slow to load some things. Like the satellite images
    from TPC. http://www.nhc.noaa.gov/satellite.shtml
    Now, they load rather quickly.

    One suggestion to users, always uninstall the other
    Java version first. It has been my experience that
    Java doesn't install over, nor remove the older version.
    So, you can end up with Java taking up a lot of space.
