Selection Tool won't allow selecting individual frame
My selection tool suddenly has a little box next to it and only allows selecting a group of frames such as a tween. I have to hold the control button to select an individual frame. I don't know what happened to change it but I can't seem to find any way to reset it. This is extremely irritating and affecting production when I'm under a deadline. If anyone can provide information on how I reset this tool I would greatly appreciate your assistance!
Thank you!
