[CentOS] Irritant

Hi again,

    I've got a nagging irritant with either putty or the man pages, or 
perhaps my setup.  If I use putty to log into my server and request any 
man page, it returns the page, but really important stuff like keywords 
are blank.  Is this perhaps caused by the wrong terminal setting in 
putty or is there something with Centos man pages that cause this to happen?

Thanks again,

Sam
