The settings in Adobe Photoshop CS5 have gone wacky in the canvas size area. Everything shows as 0, whether it be inches, pixels, etc. I tried entering numbers in place of the zeros in the height and width areas, and then it creates huge margins around the picture. If I cut the number in half to try to trick it, it still gives big margins instead of cropping the picture. HELP!
Sounds like you have Relative checked in the canvas size dialog.
THANK YOU! I can't believe I've used Adobe all these years and never saw that box! You have just made my life great again.
