I am not a graphic artist by any means but I frequently have been using CS3 for small projects. Tonight I discovered that the program is no longer able to use CTRL+E for merging down layers, which I use that hotkey pretty much all the time. Now it's suddenly not working? Can anyone explain how to restore that functionality? As far as I know I don't know how I could have simply deleted the option, as I only learned how to remap the keyboard shortcuts after the functionality vanished.
