blazar, thats because 458582 has a very long string in it's <code> section like this one: 012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789
Update tye is right: it's not the <code> tagging but the long string without whitespace that refuses to be wrapped properly.
No, the problem was that it was not in <code> tags. And your long line isn't either, despite you having put a </code> on the end of it, else it wouldn't cause a width problem for people who have their settings set up correctly for their browsing environment. Note that a long string of non-whitespace characters doesn't get wrapped if there are no newlines inside of the <code> tags with it.
