I am unable to open Photoshop files (any format) by clicking on the file in the finder. If Photoshop is not yet open, clicking on an image file will open the Photoshop program, but will not load the image. If Photoshop is already open, nothing happens. I can open these files through the regular file.open.[filename] command in Photoshop. Files of other types (Word, Illustrator, PDF, more) open in their appropriate applications. This problem is specific to Photoshop.
Using Photoshop CS under OSX 10.3.3 on and iMac G4 with 1 gig of memory.
