I have been a fan of the VPLAYER command for quite some time. I would usually use this command if a layer was added to a drawing and I only wanted it to show in a couple viewports. You can choose to freeze this layer in all viewports in the drawing and then thaw as necessary. As of the 2009 release (speaking Civil 3D and Land Desktop Companion on windows XP) the command no longer works.
Has any one else experienced this?
