Hello again Juergen,

The practical advantage of something isnt always noticed
at first.  Sometimes you have to use it a few times to
see the difference.
In particular, when you are debugging and you wish to see
variables over and over as you are doing something else in
your program, the console window gets slower sometimes
causing a delay in returning to the exw program.  This is
a real pain when trying to debug.  On the other hand,
after printing to the server it returns control to the calling
program very fast, so your program doesnt get interrupted.
The is especially true when trying to print data returned to
a Windows callback function.  
To see the difference, try printing values passed to a window
procedure with the console, then with the server.  The difference
is quite noticable.  The server doesnt make the program skip a
beat, while the console sometimes delays the calling program by
a second or two.

Also, there's no reason why this program cant be updated
to allow changing fonts and format printing and stuff like
that.  I already had ideas for multiple fonts and coloration.

If this turns out to be something anyone would like to see
in this just let me know.

Take care for now,
Al
