This is an incredible improvment to the game - I was on a friends comp who has the stock interface, and I found it unbearable to look at (much less use) after only 1 week of using this UI Mod.
However,
since installing this mod, my second chat window doesn't appear anymore, and when I go to open it (using the non-new chat window openoption on the chat window menu), it opens with a new window and a single tab, completely unconfigured.
This is hurting a lot due to my playstyle - since I keep all the "Chat" in one window and the "Events" in another. For example, when grouped, I keep my "Chat" window on the "Group" tab (where I get group and tells), and I keep my "Events" window on the "Combat" tab (which only takes the combat events that I am interested in). Non-grouped, I pull up the "Talk" tab in my "Chat" window to see ooc, says, shouts and auctions, etc, and the Events window gets the routine noise stuff (all the misc messages from the environment) on the Misc tab. Or I pull up my Guild tab, etc...
So either I go flipping multiple tabs on a single window
, or I have to reconfigure that second (combat) window each and every time I log in.
The odd thing is that it only does this with one of my toons - the other is just fine.

Is there any fix to this?
