colourise doesn't seem to function.

Hi all, I'm running a not-particularly up to date version of FR - 3.0.0 git #aaa0ed5, and it's running on vmware. Neither the vmware console or putty sessions I'm running display with pretty colours any longer, I'm sure they used to. Colourise=yes is set in radiusd.conf and I'm running freeradius -X. Sorry for the noddy question, I don't mind being flamed if something obvious.. The main question is whether it's a known issue with that version, don't want to upgrade otherwise as these are in production. Thanks Andy
