Hi Michael

I am very pleased with my custom UI but i have apperently made a small mistake since the box in the options are out off propotion.
i have tried to compare the original moi.css wit the attached one but i am not able to find the error. With the original moi.css it workes - offcause :-)
Will you be able to point me in the right direction?

Thanks !
