After changing the color of the lower gnome panel (taskbar) There is a
coordinate glitch upon re-login to that users profile. The panel will be
displayed higher up on the screen towards the upper left hand corner.  If
you were to slide the taskbar to either side (hiding the panel) it will
instantly be drawn in the proper location. This got annoying however...hehe

What I have done to get around this problem is to create two short panels
in each bottom corner (lower-left + lower right). When you log in you will
see a breif flash of the panel towards the upper left then it will be drawn
in the correct places.
