Yes, the incessant window menus doesn't help with the UI lag either. And you'd think they'd add menus for when someone invites you, instead of having to open your menu, select the party invite, then to get to the menu to select whether or not you want to join... I don't remember FFXI being so damn complicated to do the most menial tasks.

The UI lag HAS gotten better since release, but the game has a LONG way to go before it could be considered worth paying per month for.
