I have noticed that for the last couple weeks when I want to add a link to a post or page, the dialog box pops up, but I cannot enter text into the text areas. I can past into them or select from the dropdown menu, but it is really broken. No big deal for me to write the html each time. but I just found the same problem with the popup dialog box when adding a new gallery in the ngg-gallery. I don't have anything else that has a popup box so that is all that appears to be tweaked. I guess that it might be a plugin that is doing it, but I tried deactivating all of my plugins and reactivating them to no avail.
Anyone out there have this experience? I am using WP 3.2.1 with the Thematic framework and my own child theme (although I have not altered any of the admin files).
