Lost some edit functions after WordPress 3.4.2 upgrade

I seem to have lost the ability to do some edit functions after upgrading to WordPress 3.4.2. For example, when I click on Quick Edit-it does nothing. Same for trying to add an image into a post, add tags, or set the post date. Nothing happens. Any ideas? I know it is not a theme issue as went there first and they say all working fine.

Thanks!!!
