For this to work, several things happen. The speak handler gets loaded
from l:, the translator.library gets loaded from libs: and the narrator.device
gets loaded from devs:. Additionally, execute uses C:RUN to kick off the
process so if you don't have c: assigned to ram: it may cause a disk
access. It is unclear to me at this time if Execute really cares if RUN 
is resident.

The echo command (ARP echo) will print the "You need..." message if 
the arp.library gets expunged from memory and either a) it can't load
it from the current libs: directory, or b) there isn't enough contiguous
memory to load it so the OpenLibrary() fails. Personally, I suspect the
latter. Sounds like you are running right on the edge of memory availability
in your system. Run perfmon (or what ever it is called, the one with the 
rabbit icon) and watch your memory usage to see if it drops way down.
