I don't understand why Print Screen doesn't work. Yes, all these screen capture utilities are nice, but they shouldn't be necessary to capture Poser screens.

Is it possible that you have DRM software installed that prevents you from using the Windows clipboard? Some sites, such as WireImage, required such software to be installed, or you cannot view their images. It's a right pain, since it disables the clipboard completely.

Or are you using a Mac?
