I can't believe I didn't think of that! I got my own computer a couple of months ago, and hadn't been doing much with my site for a while. I recently installed the newest version of WordPress. I'll have my boyfriend try from his computer (he's asleep now). Thanks for that suggestion.
If it were a template--and I'm not saying it's not; I'm not an expert on PHP and computer languages, although I know a little here and there--I'd think the blank page that comes up with show something in the source view. But there's absolutely nothing.
It can't be just Netscape...in IE, the admin pages don't come up at all. With NS, it's just some of the results pages that don't come up. With posting, I believe it's supposed to reload the same form that I use before I submit the post; the URL in the browser shows "post.php," just like before I submit it, when it does show. If it were a closing tag, I would think I wouldn't see the post.php page the first time. But I will keep that in mind.
If things are different when I view on my bf's computer, I'll let you know. Thanks for replying. I really appreciate it.
