The reason may be that the two sites are registered to different people.

Ok. Sorry for the misunderstanding.
I mean something completely different. 
It's neither about the website http://www.gundam-seed.net, nor about http://www.gundam-seed.com.
I am working on a website (not yet online), which links to http://www.gundam-seed.net. One link refuses to accept the pre-defined CSS styles. It's a white link which is supposed to be underlined when the cursor is moved on it (hover). Unfortunately, the link does not accept the CSS commands when the URL links to http://www.gundam-seed.net. It must be some problem with the '-' in combination with '.net', because when I enter a '.com' URL the CSS style works. For instance, when I use techsurvivors.net, the link highlights fine.
I double and tripple checked the code and cannot find the error.
I have added the code of my CSS file and the HTML file. Perhaps someone of you sees the error (my guess is that there's a conflict somewhere).
The problem is where it reads <a href="http://www.gundamseed.net" class=white target="_blank">here</a>
HTML file
CODE
<td valign=top><p class=whitesmall align=center><a href="#top" class=white>Top of page</a> | © 2003 - <a href="copyright.html" class=white>GundamSEEDweb.com</a> | </p>

Thanks! 
Whoops! The title should read weird, not wired...
It's not an HTML problem. It's CSS. But it's not a CSS problem, either. It's a problem with Safari.

You are exactly correct! The "_" is the problem. Just because some browsesr let it by doesn't mean it is correct.
From Web Design Group:
"Classes may contain only the characters A-Z, a-z, 0-9, Unicode 161-255, hyphens, or escaped Unicode characters as numeric codes."
