Chris,
         It is often better to use ReadList than Run.  I always use this for 
running external "console" programs.   No command window appears and it also 
has the advantage that you can easily capture and manipulate the program's 
output stream.

Compare

Run["DIR"]

with

ReadList["!DIR",Record]

Note that you need to prefix the command string with "!".     You can also 
use Import which gives more ways of dealing with the output.

I have often wondered if there is any disadvantage to this (why is it not 
documented?) but have not found any.

Hi, please add an option to Run that can disable the command window
that pops up when an external command is run (on Windows platforms).
The present behavior becomes quite annoying when multiple commands are
run successively in a batch job.
