I am using AutoCAD 2002. My drawing window background is black. I use the design centre constantly. Within the design centre is a preview pane whose background colour is white, I wish it to be black as well so I can better see my block previews. I do not want to change my "Windows" colours globally. In the options under the display tab we can change "AutoCAD" default colours of a number of different display items. The preview pane in the design centre is not listed there. Does anyone out there know how to change this? Arie
