IE7 on XP vs IE7 on Vista

I am having an issue with IE7 and the Japanese font MS PGothic. On
Windows XP, IE 7 displays the font about 2-3 pixels larger than any
other browser on any OS. On Vista, IE7 displays the font about 1-2
pixels smaller than every other browser. This is my first site i
needed to translate into Japanese. I set the lang="ja", using UTF-8.
The fonts show, IE7 just destroys them.

Any suggestions?

Thanks
Jeff Louella
