Not sure if you've fixed your loot window issue or not..
I had the same problem. I found out the loot window width is still controled in the UI_name_server.ini file.. under [LootWnd] header. Look for width and adjust your value there...
If that doesn't fix it.. you got me.. i'm still trying to reshape all my ui mod's I've downloaded into TGA's I'm makeing to look like the Quartz ui.. Quartz is great, but alot has changed in what we can do with the xml now..
so far i have color changeing group window, the new target window, target ring, pet window.. lots of great stuff.. just moving things around and putting it to new graphics sucks.. too much time.. lol.
anyway, ta-ta for now..
