Have one user who complains that regularly she get the error message "an error message record was not found in the errmsg.b file. 19.  She says "happens several times a day". She's using the classic interface on an XP workstation.  I have no clue what to tell her as to what is the cause of such an error.    She said she got it one time going from GL-C to CL-E.  
 
Anybody have any ideas?  I've not found anything in the forum on this.
 
TIA,
 
Val
