I am having a problem with the IGUIComboBox objects. I can get them to work correctly, however, when I click on the down arrow to select an item from the list I noticed that the items to select from contain a background that is gray and transparent. My question is: Is it possible to change this back...

Yes, I am actually referring to the position of the rectangle inside the scroll bar ( not the up and down arrows, the other one! ) I will give this a try... Thank you!
