editing savedefault entry in /boot/grub/menu.lst

Hi there,
I am wanting to get a specific grub entry to be the default during the
boot process, and I am not very experienced editing /boot/grub/menu.lst
Ubuntu, kernel 2.6.15-27-686 is consistently the entry that is booted
but I want to have my windows partition as I am working on a ton of
windows projects for the time being.
I changed my 'default' setting to 'saved' and added 'savedefault'
command to the 'Microsoft Windows XP Professional' entry. I figured
rebooting XP would be loaded by default. It does not happen. Any clues
what I am doing wrong?
Here is my /boot/grub/menu.lst
---- snip ---
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from
0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default
entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved'
or your
# array will desync and will not let you boot your system.
default saved
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the
default entry
# (normally the first entry defined).
timeout 10
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu
# Pretty colours
#color cyan/blue white/blue
## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive
editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret
