    Hi,

       I have a laptop and have Fedora Core 3 installed on it. Through the
    VGA port at the back of my laptop I have my display connected to an
    external monitor.

      I configured my /etc/X11/xorg.conf file to allow Dual Monitor Set-Up
    (That is, my laptop LCD screen and my external monitor will "behave"
    like ONE LONG/BIG monitor). The xorg.conf file is attached with this
    email (also cut-and-pasted at the end of this email). I am able to
    have various applications open in the two displays and everything
    works great as if I had one big monitor!

     However, there is a BUG! When I minimize an application (say the
    mozilla browser) from the Laptop screen (i.e. my primary display)
    everything works fine! That is, the minimized window goes and sits on
    the "task bar" (i.e. the GNOME panel). Now, I can click on the
    minimized window in the GNOME panel (i.e. "task bar") and it pops back
    right up for me to continue using the application (i.e. Mozilla in
    this case). HOWEVER, when I minimize an application window from the
    SECONDARY DISPLAY (i.e. my external monitor), the application window
    JUST DISAPPEARS (i.e. I can no longer find it sitting on the task bar
    as a minimized window). Hence, if I minimize any application from the
    secondary display, I LOSE the application. That is, if I minimize
    Mozilla while browsing the net in the secondary display (i.e. my
    external monitor), the window just disappears and I cannot find it
    anywhere!!!!

     Can someone help me fix this bug/problem?

    Thanks,
    Sid
