I'll speak for Warren (hope  that's OK) since I have run into this problem
before.  Many programs allow the user to invoke a COMMAND.COM "subshell"
to execute DOS commands.  They do this by internally executing 
COMMAND.COM /C which works fine unless you have changed the switch
character.  I am fond enough of '-' as my switch char that I have
gone into several programs with DEBUG to change the /C to -C.
