This has been happening for about a week now. Is there some button I keep clicking by accident that is doing this? I have already changed my password/PIN more than once in case someone is in my account.

Maybe you're clicking on the little black cross (+) on the thumbnails. I do that a lot when I'm questing.

Oh, that's what that does? Haha. I feel quite dumb now :P Thanks!

Yup. It took me awhile to figure it out too.
