I unfortunately just had to do a reinstall of windows & after getting that done, reinstalling everything & updating drivers etc, I am now getting weird flickering black graphics in the marketplace, persona window and dressing room. I don't see this anywhere else in game and haven't noticed anything similar in other games (though I did not look in the market on Vanguard yesterday & the game is currently down so I can't check it at this time). It only happens in those places that use the dressing room view and it's the character & items that are black and/or flickering. Sometimes I see bits of the right colors but mostly it's just black. The background & windows themselves are fine.
Nevermind. Seems the newest Nvidia driver just doesn't play well with EQ2. Going back to an older one fixed my problem =).
