Title says it all. I know it's a small fix, but it was annoying in the past ... now you can finally use Command-C in an open text clipping window and be able to paste the clipping into another application.
[robg adds: This has bothered me for a longgg time -- perhaps even since OS 9 (anyone remember if you could copy clipping text then?).]
