The generic search does not include member names. That’s why “eliza” is only turning up in two threads--the word “eliza” only appears in message bodies in two of the threads. Searching on member names is a separate function. If you go to Advanced Search and enter “eliza” into the member search box, you will get more hits.
The problem that Eliza is seeing with not all of the page being displayed is a bug that appears on some system configs. It appears to be Internet Explorer only and not on every machine. I see it on my machine at work when I use IE (but not with Firefox), but not with IE on my home machine. It’s a curious bug because when you view the html source, the entire page is there, but for some reason the browser is not displaying the entire page. Given that this bug appears in IE and will likely be encountered by a significant portion of site visitors, it is a critical one that I have to get to the bottom of before going live.
