 I began developing a site from scratch on Wordpress 3.2; the visual editor
 in the admin area does not function. It often functions for a few seconds,
 but then stops completely. After updating another 2 sites to Wordpress 3.2
 and 3.2.1, I got the same problem in both. The only solution was to down-
 grade.

 This was in Opera 11.11 on 64-bit Linux. I updated to Opera 11.50 - same
 problem.

 On the most recent, I watched the Opera Javascript console for errors. On
 a copy-paste operation into the visual editor, this error was thrown and
 then the editor stopped working:

 I have the same problem. I was using Opera 11.11. I have tried on 3
 different sites, twice in WordPress 3.2 and once in WordPress 3.2.1. I
 upgraded to Opera 11.50 and the problem remains. Visual editor stops
 working. This is using Opera on 64-bit Linux.

 I found a guy in the forums with the same problem:

 opera

 Here is a Javascript Exception from Opera's log after a copy-paste
 operation; after this exception, all visual editor operations stopped
 working:
