Thanks for the explanation! It would have taken awhile for me to dig through tthe options tab and find that. It does make sense though. I am actually happy to have the ability to ignore case and slash always on, saves us a couple of seconds on every redirect.
I am also having this issue but it is only with the “ignore case” portion of the plug-in. If you view the screen shot linked you will see the box for ignore slash is checked, the box for ignore case is highlighted but will not allow a user to make the selection. It is almost as if a transparent GIF is over that portion of the form.
