check the ui.txt for what ui item is causing the issue.
It looks like SOE has an issue with thier "examine xml" according to my ui.txt

I'm not aware of anything that would cause this issue.
Try deselecting the quest feature in the thorui au then delete the folder and let it pull everything down again.

Then log in and see if it still happens.

It's all trial and error till you can track down the issue.
I could if it was a global issue and everyone was having the same problem but that doesn't seem to be the case currently so i'm left guessing it something specific to your install.
