Opera 9 and WordPress

I am using Opera 9.00 on Ubuntu 6.06 Dapper Drake with wordpress 2.0.3 on my own host, and the write page in the admin panel is giving me tons of problems. When I try to edit the HTML the things I have changed in the popup do not apply, I can’t create new paragraphs with the enter key (So I try to do it by hand with the HTML editor, and it doesn’t work!), and odd things happen with the text in the text-box (such as all the text not wrapping). Is there any way to go back to the editor I had in Opera 8.5.4 where I could do all the HTML manually? I couldn’t find an option anywhere to change it to the other editor. Any help would be appreciated, and thanks in advance.
