I'm glad it's not just been happening to me!

The first time I'd noticed it I was in Mor Dhona waiting for my Party Leader to go into AK, I think to myself that it's a bit odd that there's been no chat activity from either my Party or just anyone in Rev's Toll in general.... lo and behold I slightly scroll up on the chat area and it instantly goes to the bottom of whatever was being said that I didn't know anything about!

I normally find it fixes it just by clicking anywhere on the main screen and the text appears to scroll automatically as intended, still makes me paranoid though :l
