Okay. You know that feature where I am able to Change Owner on a thread or post? I use it on the home page to give credit to the author of whatever article I am posting there. Well, Jonathan troubleshot the problem, and that module turns out to be the bugger! So, I will disable the add-on when not in use, then enable it when I have to change owner on a thread. In the meantime, Jonathan has written to the module's owner to let them know about the bug. Thanks for helping us to figure this out, Nick and all.
