I am having a weird problem that I don't know how to fix. In CS2 I created a document that was sized 8X10. Something about it looked off so I turned on rulers to verify that it was infact 8X10. Still thinking something didn't look right I grabbed an actual ruler and held it up to the screen. And to my surprise my supposedly 8X10 was more of an 8X9 3/8ths. How do I fix this? Why was the height spot on and the length so off?
