I would like to clarify that since Q3 2012 we have made some breaking changes to our RadComboBox control appearance listed here
. We have decreased the width of the RadComboBox sprite from 2000px to 1000px. So in this case if your RadComboBox control is wider than 1000px the control will be rendered on the page with a gap between the arrow and the input field. The only solution in such cases would be creating a new sprite image for RadComboBox with the desired dimensions. I would like to clarify that if you run into the trouble with creating a new sprite image, we'll assist by providing the relevant sprite.
