Saving Your Changes
Whenever you make changes to your windows,
you must save the changes you made before you
turn off your system. If you don't save them,
they will be lost. You will have to make them
over again the next time you turn on your
system.
To save your changes, go to the section "Saving
the Changes to Your Windows and Screens" on
page 9-26, and follow those instructions.
