Centering MSN.COM home page on screen

Is there a way to get my home page, MSN.COM to center itself on my screen when I open it? It will only be centered if I use text size set to medium. Any other size and it will be too far to right or left. (The blue area on each side of main body is not the same). I like to use text size set to Large or Largest.
Thank you,

IE 7
Win XP Home Media Center

 

If I leave the "percent" level to 100% and the text size set to medium, then it is centered, but if I choose a larger or smaller text size from VIEW. TEXT SIZE, it is no longer centered, regardless of Percent level.

 

Thanks Steve, It seem's the best compromise for my "Nearsightedness" is to leave percent level at 100% and the text size set to largest. Screen is not exactly centered, but not far off.
