I'm seeing odd behavior too. It's not that graphics aren't loading, but the CSS style sheet for the various Simple Machine themes aren't completely loading. Right now, I'm looking at generic Courier and Times New Roman fonts, and no background on the page. Everything's perfectly functional though.
If I had to guess, I'd say that the CSS is referenced off-site and its source is timing out, which would make the GamesX server give up and just render what it's got.
