I have been using Adobe photoshop 7 for about 3 months on a new laptop running windows 7. This weekend I have been unable to resize the photos. Everything else works. The image size menu comes down but it will not let me change the numbers. I can move the portable drive to another computer, open the same photo & size it with no problem. I uninstalled & reinstalled photoshop 7 with no change. Any thoughts? thanks alazlo
