I can't see my properties and design center windows. The command line says the name when I click on the icon to open them but I can't see them anywhere on my desktop. If I clink again the command line says propertiesclose or adclose. When I saved and closed my last session they were open as I always have them. I work with two screens with my drawing window open in one and the other windows open in the other. I've tried using only one display but they still didn't show up. I use AutoCad 2002. I use those windows everyday. I'm at a loss without them. Any help is much appreciated.
