FC3, problem with grub after yum update?

[Al Puzzuoli]

Hi all,

I am currently running a dual boot system with  Fedora FC3 and Windows XP pro on an NTFS partition.  

After I initially installed linux, I wanted to have windows boot by default, so I modified the /etc/grub.conf and set default=1.  This worked fine until I did my first yum update.
After the update, I noticed that by default, the system was again booting Linux.  I checked the grub.conf and noticed that it had reverted to default=0.  I changed it back to default=1; However it no longer seems to be honoring that parameter, as it still boots Linux by default.

Any suggestions as to how to fix this would be much appreciated.

TIA,
