Eclipse Copy not working

I always had a problem with Eclipse under Linux whereby Copy (Ctrl-C) rarely worked first go. I learned to copy twice to ensure the text was placed in the clipboard.

I've happily run Eclipse on the Mac for more than a year now without such problems. But last week I let 3.5 do a self update - just a few minor updates bringing it to 3.5.2.

Afterwards Cmd-C became unreliable much like under Linux.

Anyway, I found a fix. Open Eclipse's main preferences. Go to General->Keys. Search the key bindings for 'Copy'. Erase the key binding (which will show "Cmd C").

Cmd C now works. Perhaps Eclipse and MacOS were both trying to capture the keypress and neither got it correctly.
