I know of no reason for TVFLG especially to be doing something odd. 
Perhaps the binary that got copied has an error.  You could delete the 
load mode ($LOAD/TVFLG.EXE) and run the MNJ.  Actually I have made a 
change to TVFLG so if you do this tomorrow, TVFLG would update anyway.

Does SPFLG work with the same adverbs, does UVPRT, VPLOT, etc work with 
the same adverbs or do you change them at all between tests?  The flag 
all IFs or all channels may be affected by whether there is more than 
one IF or channel in the current execution (I don't really know).

The MS for user 1 message can be eliminated by logging in once as user 
#1 (password AMANAGER).
