ncstudio display problem

[chrisallen]

Hello, Ncstudio has been fine for over a year now but today the display seems to have gone out of range of the monitor. I cant see the top or bottom lines anymore which is a real hassle. I must have done something but can't figure out how to get it back. I've closed it and re-opened it and even tried re-starting the computer. It's running on an old XPmachine.
Any help appreciated.
Thanks.
