It should now be fixed - the error code was set to tell of the CLRHIS 
(which I find now is a correct message since I missed a preceding test) 
and was not reset when returning to higher levels.  They got upset and 
died.  Fixed by resetting the error code before going to the higher levels.

Thanks for being both a careful user and sticking with error issues 
until resolved.
