Some common errors:

• X server insecure (must use xauth-style authorization)

Tk requires you to have a secure X server before you can use the send command. See http://ce-toolkit.crd.ge.com/tkxauth/ for instructions on how to make your server secure.

• extra tokens at end of expression while executing [information appears to be missing here]
