Since the 5/29 update the following happens in WO-A every time:
 
Enter first WO and all goes fine.
Enter second WO and after pressing Save I get the this message:
"WARN ERR-File: T7WOA.SRC Line 561
An error message record was not found in ERRMSG.B file 404"
 
Then the program (T7WOA) quits.  I open it back up and the cycle starts all over...
