ok, got the extension, installed it, activated it, restarted. (OS 9.1)(PM
5400)(B20)

Running as StandardBASIC type with a  cpuPPC.

Commented out:

    COMPILE LONG if def  _usingliteRuntime = _false
       COMPILE SHUTDOWN "*** Only Lite Runtime! ***"
    COMPILE END IF

Placed file - mvusd.html - in the same folder and in the root directory.

Changed line in URL Test.main   to read:

   urlText$ = "file://mvusd.html"

Program compiles and runs.
Responds with 
    " URL: mvusd.html"
    "File size: 0"

Machine freezes forcing a "Ctrl-Alt-Pwr" reboot.

I found this on Apple's Software Updates site, but it requires OS 9.
