so I tested this myself again and I think I see what you mean--you can walk around but not move the camera even if the dialogue has not been cycled through yet (by pressing enter or space). So to get out of the locked state press enter or space, the dialogue will disappear and you can walk freely. However I will work on a quick patch right now to ensure you are fully locked and it shows the control on screen just to get rid of future confusion lol
update: patch released for redownloading!
