Can't Name New Instance

When I add a new instance of Tutorial Server on the management console, it pops up a box to type a name into with the instructions "Press enter to submit the new instance name for application. Press ESC + SHIFT to cancel". Neither enter nor ESC-SHIFT seem to do anything; the View Applications screen is permanently hung up on trying to name the instance. Any ideas?

(The console and server are both running on Fedora Core 5).
