I had glitches after upgrading to 10.2.3 in multiple applications and of various flavor. They all disappeared after installing the Combined 10.2.3 updater over a 10.2.0 installation.
The last glitch remained though and went away only after some "sudo rm." The problem was that the Services menu in all applications was empty, and that cut, copy, and paste were not functioning (paste inactive, clipboard empty).
The problem disappeared by removing the content of the following directories, .DS_Store files included:
~/Library/Caches (your local Library directory)After this, the clipboard was again functioning as well as all Services. As always, be wary when using sudo commands as they will execute as if you were god (don't wipe out your system).
/Library/Caches
/System/Library/Caches
/System/Library/Extensions.kextcache
