auto log in problems sine CentOS 5.3

[Todd and Margo Chester]

Hi All,

I have gdm configured to auto log me into to
XFce.  Since upgrading from CentOS 5.2 to 5.3, about
one in five reboot (I power off at night), the
auto log on fails and I get the gdm prompt with the
various profiles on it.

Does anyone know how to fix this?

Many thanks,
