Problems changing modes on new RPi image

Hi guys just tested the new image found problem changing mode to suit my monitor, checked the configure folder in the !boot/predesk folder there is a Line not the letter L in the obey file monitor, If you change it to an L it works.
how ever when or if you change with !configure app it it puts the Line in not the L back to square One.
Not a Bug the Fix is in the post about CMOS in general section.
Thanks teach me to read all the post before i go off half cocked.
