For some unknown reason, every once in a while this glitch in OS X will happen to me. When I right click on a file and select Open With I will see all of the associated programs listed twice! Depending on the file type, it can sometimes be a very long list when duplicated.

You can easily use Onyx, a terrific free utility to correct this problem. Please note that Onyx is a very powerful system utility. Don't play around with features that you aren't sure about, there is the potential to mess things up if you don't know what you're doing.

The first image shows how all the apps are listed twice. The next image shows what to execute in Onyx to fix the problem, and the last image shows the Open With list corrected.
