Hi, I've got a gripe with OS X - well, a new gripe to add to the list. I've been downloading and applying new icons for a couple days. Now I'd like to edit one to create a custom icon. I tried opening the icon file in Photoshop, no go. So I checked what extension it was by enabling 'show all file extensions' in the Finder preferences. Sure, all file extensions show up, but none on the icons. I believe they're PNG images, but when i rename them as PNGs Photoshop still can't read them. When I put the fiel on my USB drive to try it on my Windows machine, the file shows up as a 0kb, extension-less file. What's going on? I'd appreciate any input on this one, I'm sure there's an explanation out there. Screenshot!
