Question: Cannot Plot: Menu Greyed, and Command line does not work as well.


I am using Maple 13 under Linux and cannot seem to plot.  I get a message like

Error, (in plot) type `has_unit` does not exist

Furthermore, the Table, Plot, Drawing and Spreadsheet menus are greyed out so I cannot access them.  How can I rectify this?  Are these features disabled for some reason under Linux?
