Hi Ian,

your analysis is spot-on. Classical cut-and-paste error, I'm afraid,
and it is also present in the current 4.3.0 code. So I'm glad You
spotted it!

A diff for 4.2.3 is below. For 4.3.0, I'll commit a change later today - 
there are some other fixes in the same area of code that I am working
on (relating to the Windows client SVC checks).

Regards,
Henrik
