Pixel font in centered mc

Hello
I’m building a site where i use this AS to put my main MC always centered on stage when/if the visitor changes the size of the browser window. http://www.ffiles.com/flash/actionscript/mc_align/

The problem is that i want to use a pixelfont on my site, but if i change the size of the browser window and the main MC ends up on a X/Y value wich is not a whole pixel the pixelfont gets blurred… Im guessing this could be solved by the math.round function or something? But im no master at AS so i could use some help.

thanks
