I wish there was a confirmation required when changing image size. I want 640 pixels and don't notice it's set to "inches" and it takes forever to resize to 640 inches. If it stopped me and asked "are you sure" it would be a great help!
yes, thanks, but i go quickly and assume the drop down is pixels... I just think if you're changing a 1 inch wide picture to a 45 foot wide picture, Photoshop could stop you and ask if you're sure! It reminds me of Apple's old iPod. If you had auto back-up set up, and connected an empty iPod, it would erase all 4,200 songs in your library without flinching. They fixed it in a later update.
