Dear Sir:

I am happily using your Geomview.  It is so great!
And, what I like on Geomview is that the people of Geomview
are very kind and fast for the answering of my questions.

I have three questions.
  
1. I tried to use "Commands" on PANELS menu.  I tried "clock" for
testing.  However, I have the following message:
	"clock: No such file or directory".
I don't know what is wrong with my Geomview.  Is this means
that my installation is wrong or I used wrong command format?
  
2. Is there any data format for a set of 2-dimensional polygons? 

3. How to shade two sides (front and rear) of one object with
different colors and with only one (front or rear) normal vector? 

Best regards,



Tae-wan Kim
