Regarding the letter:  it is the conditional formatting that is the problem.  Profile selects which 'messages' it inserts depending on the conditions in the return.  I HAVE modified the phrase concerning instalments.  We prefer to let CRA send them notices of expected instalments.  BUT there are several spaces inserted between other paragraphs that, depending on the message sent to the client, causes it to leave great gaps in the letter.  It looks very cheap.  

I've attached a screenshot.  This is NOT the worst, but a recent file fresh in my head.
