contact list display names don't update

[ShadowTech]

Hello, I don't know if this has been reported before, or if it's even common or has been noticed...but...

I have noticed that if a MSN contact changes his display name after my contact list has loaded it in, it won't change unless I use the little minimize triangle to open and close the list again, which in effect refreshes it.

How was I even able to figure out names weren't updating?
The mouse-over window that pops up if you hover over the contact list. That seems to always grab the most recent display name for a contact.

I hope that made sense, I'm just wondering if anyone else has seen it before.
