Scene Release Time on Road Hog

So when I go to try and change the release time of a scene in the scene directory I can't change the time because when I go to click on the lower right hand option that pops up, the screen acts like I am trying to drag my finger across and as soon as I take my finger off the scene that option in the lower right corner goes away. Am I not doing something right or just what do I do?
