[Chimera-users] Background image

Hi, I need help to put an image in the background of the main chimera window. I am using the background settings dialogue in preferences and after loading the image it does appear in the little icon in the dialogue box but not on the main chimera window. Do I need to do something else? The image I am trying to place is in jpeg format and I am using Chimera version 1.6 Thanks Hernando
