How do I stop the computer from opening multiple versions of a program, such as PhotoshoP
With Photoshop open, I right click a photo on the desktop and choose "open photo with... photoshop" and it opens a second bouncing version of PSE in the dock. I reveal location of both, and they are the same. Why is this happening, and how do I fix it? Thanks!
Mac mini, OS X Mavericks (10.9.3)
