Very strange Bill. I assume you have stopped and restarted DoubleCAD, have you rebooted?
It may be a corrupted config INI. In that case you'll have to delete your Built in folder so DoubleCAD can rebuild it.
close DC
go to, in your user folder,
>AppData>Roaming>IMSIDesign>DoubleCAD>3>XT>Data>Profiles>Built-in
delete all the contents of that folder.
