help dosn't work

[Salvatore]

Hi , 
I'm having a problem after an upgrade of TSM 4222 server, from a prevously version 
4210, on AIX 433.
The help on line dosn't work, when i try to use a simple help command, for example 
HELP REG LIC, 
i receive an output that is on a 1 line whithout carriage return.
Can anybody help me to fix this?
Many thanks in advance.
