Difficulties with Front End and with mysterious messages

I am having difficulties with the Front End. I am running X under
Solaris. Are there instructions provided for operating the FrontEnd,
other than the Mathematica Book, which seems to miss out some important
points.

How do I save a file?

While in a notebook, I selected the File Menu. Then I selected Save
As...
But I was unable to modify the filename given. So I had to save it as
Untitled-1.nb and then go into the Unix shell to rename it to something
sensible.

I tried to write a file from the notebook, with the command

Display["cpos.eps",%,"eps"]
and I got the answer
LinkObject:: linkd :
<<1>> is closed; the connection is dead.

I was unable cut and paste from the Mathematica window to the Unix
shell. Is there any way to do this?

When I tried reloading the program, I was unable to modify it from
inside Mathematica. After executing, the prompt shows a black circle
with a horizontal line, which looks like a no-entry sign.

Here is the notebook:

(***********************************************************************

                    Mathematica-Compatible Notebook

This notebook can be used on any computer system with Mathematica 3.0,
MathReader 3.0, or any compatible application. The data for the
notebook  starts with the line of stars above.

To get the notebook into a Mathematica-compatible application, do one of
the following:

* Save the data starting with the line of stars above into a file
  with a name ending in .nb, then open the file inside the application;

* Copy the data starting with the line of stars above to the
  clipboard, then use the Paste menu command inside the application.

Data for notebooks contains only printable 7-bit ASCII and can be sent
directly in email or through ftp in text mode.  Newlines can be CR, LF
or CRLF (Unix, Macintosh or MS-DOS style).

NOTE: If you modify the data for this notebook not in a Mathematica-
compatible application, you must delete the line below containing the 
word CacheID, otherwise Mathematica-compatible applications may try to 
use invalid cache data.

applications, contact Wolfram Research:
