IE7 - Loss of focus for the second time to edit a link

It's a case that only happens to me with IE7 (with Firefox, IE8 and Chrome works well). I use Ckeditor 3.5.2.

If I edit a link for the second time, I get a javascript error referencing a loss of focus. Same happens if I edit an image a second time. The javascript error is the same, but on another line. Mistakes are the file "_source / plugins / dialogui / plugin.js", lines 1039 and 1021:

Line 1039

// GECKO BUG: setTimeout() is needed to workaround invisible selections.
setTimeout( function()
{
     var e = me.getInputElement();
          if ( e )
     {
          e.$.focus(); //************* ERROR ****************//
          e.$.select();
     }
}, 0 );

Line 1021

// GECKO BUG: setTimeout() is needed to workaround invisible selections.
setTimeout( function()
{
     var element = me.getInputElement();
     element && element.$.focus(); //************* ERROR ****************//
}, 0 );
