In general you are on the right track.

The problem can raise on any DBX based command at any time, depending on your program. A grid getting focus, a timer fireing, a function that does not reset to the right area. A inserted SQL SELECT.

There are only two ways

SELECT infront of everything DBX
But again it might fail too because the shift can happen between two comand lines

Use SQL commands to do the work. They clearly adress tables

Note that stuff like REPLACE ... IN Alias will not solve the problems. It has it's own traps.
