[racket] Cut, copy, and paste keybindings not working on OS X with Racket 6.1

I just installed Racket 6.1, and noticed that the standard cut, copy, and paste keybindings aren't working on OS X 10.9.4. The Edit->Keybindings->Show All Keybindiings dialog shows that they are set to d:x, d:c, and d:v. 

Undo, which is bound to d:z, works as expected. Cut (Cmd-x) doesn't appear to do anything; paste (Cmd-v) acts like it is being interpreted as esc;v (previous-page), and copy (Cmd-c) acts like it is being interpreted as esc;c (capitalize-word).

Best regards,
-Steve
