sudden disappear of visual editor

same thing also happened here..
for those of you who get a blank page when trying to write a new post, switch to Mozilla Firefox..
and for those of you who can’t get the rich edit box, try this plugin…https://www.deanlee.cn/wordpress/fckeditor-for-wordpress-plugin/
this should bring you more fuctions..

This is what i did to solve this problem:

rewrite code in tiny_mce_qzip.php to false
reinstall wordpress
deactivate and activate all plugins
deactivate wp-poll plugin
clear browser cache
refreshing the page
deleting tiny_mce cookies
opening in Firefox & IE7
re-checking “use visual editor” in my profile page
update tinymce from official site of this function

BUT MY PROBLEM IS NOT RESOLVED!
I can’t use visual editor in any browser, after all of this hacking to decide this problem.
Wordpress team must pay attention to this bug!
I’m using WP 2.3.2, Firefox 2.0.0.11, Windows XP

POSSIBLE SOLUTION FOR SOME”
I experienced a similar problem with the Visual Editor simply disappearing recently, and by chance managed to solve it. The culprit in my case was Kaspersky Anti-virus. By changing the Web virus scan method to “Buffering Scan”, the problem was resolved and the visual editor is back in WordPress! (I was actually searching for a solution to youtube videos taking forever to display on my pc, when I came across a reference to the Kaspersky Anti-virus issue). Then I realised it might be what’s causing the editor problem as well.
Bottom line: Problem solved and I’m happy again!
