This should not be happening and you can definitly scroll in story.
Can you inform us of the following:
1) Platform you are on and
2) Whether you are working on browser or desktop app
so that we can reproduce the issue at our end?
Also is this a consistent issue or you are facing this with some particular scripts only?

Thanks for your response. The delete/backspace issue has been resolved. I'm not sure what I did but after a reboot it all worked fine again.
Ever since I installed the software which is the desktop I have not been able to scroll. I'm working on Windows 7 Home Premium - Microsoft Windows Version 6.1 (build 7601: Service Pack 1)
