GlobalTuners:Ghost users

We have different kinds of ghost users:
 * 1) Users who show up in both the receiver Info and Status pages
 * 2) * Most likely cause: the flash interface did not properly unload on the client's computer
 * 3) ** Solution: kill the user's browser completely, or reboot the user's computer
 * 4) * Less likely cause: some bug in the RadioServer software
 * 5) ** Solution: restart the RadioServer software or the server computer
 * 6) Users who show up in the Info page only
 * 7) * Most likely cause: a bug in the RadioServer software (fixed in version 3206)
 * 8) * Less likely cause: a new bug in the RadioServer which somehow causes desynchronization
 * 9) * Solution: restart (or kick) the RadioServer (not the user!), or restart the server computer
 * 10) Users who show up in the Status page only
 * 11) * Less likely cause: a new bug in the RadioServer which somehow causes desynchronization
 * 12) * Solution: restart the RadioServer, or restart the server computer
