I have a MacPro 1 (64 bit) and Adobe CS5. I am trying to get the Epson 1240 Twain to show up in Photoshop's Import menu. I uninstalled all Epson drivers and downloaded and installed the latest 1240 driver from Epson. I can scan into Preview, and it works quite well, but I cannot see the Twain for my scanner in Photoshop. Does anyone know how to make this happen?
