Typing fails in "Manage Extension" form

When I attempt to edit/change the name and email address of one of the existing extensions, the fields do not accept all keystrokes.

For example, cannot type an “S” or “s” in those text boxes.

Happens on an iMac, OS 10.8.4 using a macally ikey wired USB keyboard.

Contact me if you need further.
