Yes, you are getting a little confused. :-)

It is not enough to simply close the PostScript file, you must also
switch back to your normal graphics device (X, in your case), if you
want to create graphics windows with plots and maps in them.

The normal sequence of commands looks something like this:

thisDevice = !D.Name
Set_Plot, 'PS'
Device, ... ; Configure PostScript Device
.... whatever graphics commands you use go here....
Device, /Close
Set_Plot, thisDevice

In this way, you will be set up to do "normal" IDL graphics again.

Cheers,

David
