Does not work in WP 3.5 All write permissions enabled but the images do not get uploaded.
When the images fail to upload the post does not get added
When the above fails there is no warning to the user.
Before java was enabled a user could upload a single image. Once this was changed to java enabled all images then fail as does the post.
When changing back the problem still persists and the whole form does not work.
Needs some serious work to rectify all the above before it is used. Wait for next release if there is one to see if there is any progress.
When you deactivate and remove (Including settings) It does not completely remove the scripts or the settings.
