I am using Gnome window manager on RedHat Enterprise Linux v2.6.9-67 and recently my Gnome sessions started behaving differently and I do not know what I did to cause this or to restore the old behavior.
Previously, I had icons for each window along the bottom of the screen in a bar, now there is still a bar, but no icons for windows appear. Consequently, once a window is minimized, I cannot find anyway to raise it again. Starting a new Gnome session from scratch has same behavior.
Please suggest what I can do such that I can create a Gnome session where I can re-raise windows after minimizing them by having their icon appear again along the bar at bottom of window?
