Also, I’m not sure it was an Opera problem. I think I also had it with IE.

As near as I can tell, what’s happening is that the Opera/TinyMCE combination is instead using a   any time there are two “spaces” in a row—and it’s counting line breaks. So if you start typing at the end of the text area, it’s fine, but if you go back and start typing at the end of a line, all the spaces get inserted incorrectly. There’s only one flaw in this theory, and that’s the fact that if I enable the WYSIWYG editor on my own site, the bug doesn’t follow this pattern.

I know support for Opera in TinyMCE is new, since it relies on designMode, which is new in Opera 9. So I don’t know whether it’s a flaw in Opera’s implementation of designMode, or a flaw in the way TinyMCE interacts with Opera.

I did look at the JavaScript code for the version of TinyMCE that’s included in WordPress, and I found what looks like a disabled workaround for a similar problem in Gecko on line 967 of /wp-includes/js/tinymce/tiny_mce.js — but re-enabling it and setting it to check isOpera instead of isGecko didn’t have any effect on the problem.

(Personally, I disabled the WYSIWYG editor shortly after upgrading to WordPress 2.0 because I didn’t like the code it generated. That, and I’m so used to HTML that typing the code was faster than trying to use the toolbar.)

Or was it on the actual post/preview page?

(Nice layout/graphics by EC and Dhalvat, as well.)

Wow, cool live comment preview and auto-gen browser/OS info, too…

It appears to me that wordpress thinks the whole line is one word, with no spaces. If I double click on a word in the editor, it’s supposed to select only that word. However, if I click on a word in the long line, many words get selected.

As for WordPress and word wrap… it looks OK, at least on this post. what is it that you’re having trouble with? At least with the default setup, it will convert returns to line breaks, double-returns to paragraphs, and if you just type without hitting enter, it’ll wrap it normally. (Assuming you’re using the plain posting interface, anyway.)

If you want to justify the text, that’s done in the CSS file for the theme you’re using. Look for a .post {...} section and add text-align: justify; line between the curly braces. You could do th same thing for comments by editing the .comments {...} section.
