XCLIP

The manual and the HTML readme file says Intellicad 2000 supports XCLIP. The manual even explains how to use the command. When I try to use the command, however, all I get is a message stating that this command is not yet supported. When I receive files from clients with XCLIPed XREFs, everything seems to display properly, but I can't use the XCLIP command. I am using ver. 2.2.0027.
