For the people coming over from the Download forum, here is the answer for the "only 1 chat window" problem (and a bunch of other related problems, like wandering bags between saves, etc)). Its not a custom UI thing that causes this; its a long known Sony bug, and they have yet to fix it
.
What happens is the settings on the server corrupt the character.ini file on your disk. So download a
Character.ini replacement file from the downloads area, and it should work. Directions are in the thread below that download - follow the link (the original source for this fix was another thread and it got cross posed to here - I just gave it its own DL area, so its easier to find if you need it again).
It seems this got worse after update 10 and all the tinkering with the fonts by SOE.
But that file should help. My advice is once you get things where you like them, copy the ini file out as a "known good" and use it next time your file gets corrupted (or copy it in evey time jsut before youstart your game)
