I have an IMac G4 running OS 10.3.9 and I have Photoshop CS, using a HP Scanjet 3500c. I can't get Photoshop to show the Twain plugin when I go to Import menu, the plugin even shows up in the Adobe plugins folder. Does anyone know how to get this plugin to work? I've searched like crazy and cannont find a driver or anything any help would be awesome..it's super annoying to have to open 2 programs to just make a scan.
