List formatting issues

Any ventures on why this list will show in all browsers except Fx 3.5 + ? It worked fine until an update of the member base, effectively doubling the list. Fx cuts it off @ 194 users, about half of the old list, which previously displayed with no problems.

PS. User 194's name is lost as well. I have choppe开发者_开发知识库d this into pieces, leaving only 10 extra users, same result- no joy.

Ordered List

Update: The link no longer demonstrates the original problem. The original page included a large set of nested tables, which were missing proper closing tags.

Have you considered </center> tags?
