18139,Visual editor non-functional in admin area on latest Opera (64-bit Linux),DavidAnderson,,"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: http://wordpress.org/support/topic/wordpress-bug-admin-are-problems-in-opera

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