Hello Michael,

Wow I like hearing that positive feedback about the speed!  Thanks!

I'm not sure I understand your issue yet though, but I'll give my quick
thoughts on your email:

- yes multiple versions of MS4W can be installed on the same machine
- the simplest way to install multiple versions is to use the installer,
which will magically change the name of the Apache service so you can run
each MS4W separately, for example:

  step1 - install: http://www.maptools.org/dl/ms4w/ms4w-3.0.2-setup.exe
          - leave the port as 80
          - the Apache service will be named "Apache MS4W Web Server: port
80" by the installer

  step2 - install: http://www.maptools.org/dl/ms4w/ms4w-3.0.1-setup.exe
          - choose a different install location (anywhere)
          - specify a different Apache port, such as 8080
          - the Apache service will be named "Apache MS4W Web Server: port
8080" by the installer

I do that for my testing and it works great, allowing me to have many MS4W
installations on the same machine.

Hopefully my thoughts help a little.  And again, thanks for the positive
