I also get to this point OK, with a grid instead of the IB_Edit. I can
connect to the database in designing mode. But when I try to edit the
query's SQL, I get:

ISC ERROR CODE 335544344
ISC ERROR MESSAGE
I/O error for file 'C:\EMPLOYEE.GDB'
Error while trying to access file
The handle is invalid.

Sorry about what must be a very basic question, but I can't for the life of
me see any difference between what I have done and the tutorial (which is
great, BTW). And my archive of this list does not go back very far so a
search of this, and the help file, has revealed nothing.
