Yes, the procedure executes and finishes properly.
It's started by an Command Button from the Forms Tool Bar, which is
located on a worksheet.

I fear I have to look deeper into my colleagues "spaghetti" program,
this was what I tried to prevent with my global question.

I tried some ideas, what might have caused the malfunction,
but only when I closed the workbook with the procedure I have called
by VBA than it doesn't come back.

Anyway thnaks for your reply.
