The actual release have a load of bugs... don't know why, but a lot of changes to the latest releases are bringing some wysiwyg problems, like reported in the forum, and the upload.php section is making a mess...
when i see the upload form, i now have the non-javascript form when displaying the uploaded files, and when i want to see all the files, i have each file displayed twice...
also, a request about the upload form... can you apply the same style that we see in the admin pages everywhere?.. actually it have its own style, and it doesn't fit well... as the wp-admin.css if called anyway, why not apply that style by default so we don't have a strange look ??
