So I'm not fully comprehending what in the world this problem is. I've been running through the tutorials in the book. They've really been helping me out, but I got a problem. On lesson 5, where you learn how to create loops such as walking, running, sitting, and etc. Well, I was pasting the final frames, you know, where the mirror pasting is put, and I made a mistake. I accidentally placed a mirrored paste, when I wanted a normal paste. So I quickly did undo, and tried to paste... It wouldn't work, I don't know what it is. For some reason, it just wont let me paste on the final frame. I tried deleting the frame, and so on. I'm working within the time line setup up of managing the frames. So if there is some way to actually highlight the frames and delete them, please let me know.
If anyone can help me on this problem, I would be very appreciative. Thank you very much.
*EDIT*
I wish I could delete this. After mere seconds of just posting for help, I fixed the problem. My apologies for clouding up the topic forum.
