Question about mivng the letterbox position (not size)

[rasgryphon]

In my current interface I have been using /cl_letter_box_position to change the lettrbox frame to the bottom only. Is their anyway to make this permanent? (currently i have to type the command eveytime i log in) Also when I go underwater, the frame switches to the top, then back to the bottom when i am not under water, does anyone know a way to stop that from happening?

Thanks
