 * The dashboard is fine for me using Opera 11.50. Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Eleven theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.
 * – re-uploading the wp-admin and wp-includes folders from a **fresh** download
   of WordPress.

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

 * I’m having serious Opera problems as well since upgrading. These problems happen
   on multiple sites on multiple web hosts on multiple themes and plugin configurations.
   What can we do to help fix this problem?

 * Recently, I have discovered (and fixed) a bug in TinyMCE, which Livefyre uses
   and also has the bug.
    For the “getRangeAt, INDEX_SIZE_ERR” JavaScript error,
   have a look at my blog post.
 * TinyMCE JavaScript error in Opera (getRangeAt, INDEX_SIZE_ERR):
    [http://my.opera.com/XP1/blog/2011/07/21/tinymce-javascript-error-in-opera-getrangeat-index-size-err](http://my.opera.com/XP1/blog/2011/07/21/tinymce-javascript-error-in-opera-getrangeat-index-size-err)
 * See my pull request here:
    [https://github.com/tinymce/tinymce/pull/77/](https://github.com/tinymce/tinymce/pull/77/)
 * Let me know if testing reveals that it works or doesn’t work.
 * This TinyMCE bug was previously reported from at least 2011-04-14, yet has not
   been fixed (until now, hopefully). See TinyMCE bug reports [#4306](http://tinymce.moxiecode.com/develop/bugtracker_view.php?id=4306)
   and [#4372 (duplicate)](http://tinymce.moxiecode.com/develop/bugtracker_view.php?id=4372).
 * This one JavaScript error is what seems to be causing all types of problems, 
   including the CTRL + V paste bug and the underscore bug. I fixed the bug and 
   submitted a pull request (see above).
