Today a colleague of mine encountered a strange behaviour with Photoshop CS6 64bit on a Win7-PC (also 64bit), which I could reproduce on a second machine.
Highlighting severeal jpg-images in a folder and hitting the Enter-key opens
The same effect happens when I use the "Open with..."-command from Windows Explorer on the images.
Does anyone know this issue?
Normal behavior. Windows only allows a given number of files to be handed over via DDE and that's what happens when a process is already active. When you do this with no program open, it simply blindly fires a standard command with only one file as an argument, but does so for every single file. That's why it works then. Nothing you can change. It's a limitation in Windows itself combined with the fact that only one PS process can be active....
Thank you for your reply! I've just performed a test on another machine (win7, 64bit) with Photoshop CS5 installed. All images open in this enviroment without a problem, even when Photoshop is already running.
