UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support Web TV doesn't see forum?

Hi--
Got a user who accesses the Web only via WebTV. He sent me this message:

Doug, I went to the Leader Board site but there`s nothing there except large areas of black. You can click down and you get highlights, but there is nothing to bring up . I don`t know whether it`s my WebTv system, but just thought i`d let you know.

So I told him I'd ask my gurus--you!
Am running php 5.1.5, pretty much plain vanilla, except the default skin is largetheblues (so Nutscape users can see it). Is there a basic incompatibility here, or do I have a wrong setting, or do I have to tell him to change something on his end?
Any ideas? What questions do I need to ask him?
PS: To go where he went, click on the blue box, "The Leader Board" at the top of my home page.
