I have a global error handler for my application.

on error do error_handler

...

procedure error_handler
linedesc = message(1)

Being in IDE message(1) returns a correct description of the line executed ; but when we run .exe from Explorer it is either empty or something strange ( couldn't figure out such a line existsthe .
.Exe is built with debug checked.

Is this expected behaviour ?

Thank you.
