First, thank you for your prompt reply. Ok, I understand what you are saying.
How come the aProgStack has a call to my APPLICATION_SETUP.START method? Is it because this method has the READ EVENTS that it is not cleared from the stack?
Would your explanation tells me that since the GO_NEXT code comes across an error, there was no error in LOAD and INIT methods?

UPDATE. Here is what I am trying to find. When a user clicks on the GO_NEXT button, the code comes across a problem where the main cursor of the form is lost. That is, the SELECT("Main_Cursor") is 0. And I am trying to find where in this form (which is quite complicated) the cursor is being closed.
