by the way, you don't need to be able to see your name in colour for others to see it (e.g. if I sign into Messenger on my dad's computer or girlfriend's or someone else who doesn't have Plus! as of now) I wouldn't see my name properly but others will

also if what djdannyp suggested isn't the problem you might want to tell us what version of Windows and any other Messenger addons you're using
