heres as Screenshot of my UI
It used to be fine but after switching characters to copy the UI I came back to this one to find my hotkey bars where messed up - not only are verticle bars bigger (and blurry) than the rest, the others seem to have shrunk!
Arround the same time I also got the "Zooming" bug that prevents mouse wheel zooming in and out of your character so I figured Id quit DDO and try again. the zoom bug fixed on restart but the UI is still messed up.
I run DX 11 with 1920 x 1080 res with all the bells and whistles up high on a GeForce GTX 460 (windows 7 64).
