Having a program which uses the ARP requesters work doesn't really
count, David, since the return from the requester includes the
complete path name of the file.  What I *should* have said was that
I'll bet that any program, started from MyMenu, which does an AmigaDOS
CurrentDir() call, such as VT100, will crash the system.  I suspect,
as I said originally, that MyMenu is neither perfectly duplicating the
CLI startup environment (which is very hard--ask Bill Hawes) nor
sending a completely proper WBStartup message, i.e., one *including* a
legal Lock on a directory.  VT100 requires one or the other for its
CurrentDir() call.
