[Tutor] interpreter restarts

[Eric Brunson]

Sara,

Stick with ssh, IDE's are a crutch.  ;-)

But that's just my opinion, others may differ.

However, if you were running an X server on your local machine, you 
could use SSH to allow you to run GUI programs from your remote server.  
There are a couple of free X servers for Windoze, but running Linux on 
your local machine would give you the greatest success.  If you are 
interested in pursuing this, google up and install an X server, then 
post back.

Sincerely,
e.
