I don't have the latest vt100, but I use it with MyMenu (I wrote it).
In fact, if I recall, I put vt100 as one of the examples in the MyMenu
docs.  (I don't have the latest ARP either, so that may be the
problem)

MyMenu passes a directory lock if the program is defined as WB, other
wise it just does a "run".  I have only tried running vt100 from
MyMenu as a workbench program, not as a CLI program, so you might try
doing that and see if it works.

Needless to say, I don't duplicate the CLI environment (there's a lot
of stuff there), but wouldn't a NULL lock imply the boot disk?  There
was a lot of stuff I didn't put in, paths, etc., to save some space.
