I have the same problem. I can’t select/cut text in the Text Widget. There are a couple of lengthy topics about this but none have a resolution to the problem. I have had the problem in IE7 and IE8.
Sonance, how can I confirm that your modification is working? I checked the HTML of Tag Cloud and don’t see any nofollow attribute in the links. Thanks.
So what happened to this? I’m also struggling with the alternate text. I can’t get it to work even when I’m using a caption. No matter what I do the alternate text is always the file name of the image.
