The Monastery Gates often needs to scroll for me too, using Netscape buggy.72 under Linux. What's going on there is that a post has embedded code that's too wide for the display.

Code, marked by the <CODE> tags, displays in a slightly larger than normal, monospaced font. It's not subject to automatic line wrapping, either.

The solution is to edit the offending post, if possible, or for petitioners to be careful about line widths. There may be something specific that offends IE5, but I notice the same thing on many writeups, so it's not just affecting you.
