As I said in my previous post: If you scroll down on a thread here on this forum, you will find that the icon is not in the correct location, and disabling AUT will not fix the problem (I tested it).
Thread Information, where the post collapse icon is located on this forum, is not the correct location, and disabling AUT will not cause the icon to shift position down to the Members Who Have Read This Thread block that it controls.
You can test it yourself by moving the User Tag List to the top of the thread rather than the bottom.
